Gas Analysis on Cement Plants

Transcription

1 Gas Analysis on Cement Plants Continuous analysis of process gas is a compulsory and fundamental task for any cement plant working in a competitive market. The process benefits are harvested in a number of areas with very favourable returns on investment such as optimisation of combustion, reduction of fuel consumption and improvement of clinker quality. Our continuous emission monitoring and reporting system may be configured to be in compliance with any legislative demand, allowing cement plants to focus on producing cement.

2 Kiln Inlet and Calciner Gas Analysis - KilnLoq KilnLoq probe mounted Probe Cleaning Panel Water Control Panel GASloq 1200 Heated Hose Fig. 1 The FLSmidth gas analysis solution for the kiln inlet is designed on the basis of on-site experience. The equipment configuration is modular for fast installation and commissioning. The equipment is specially designed for easy trouble-free operation and maintenance in the very demanding environment and process of a cement plant. All power and external connections are terminated through the GASloq 1200 panel. Standard interface for FLSmidth Automation ECS is included and optional remote access can be provided. Application The Kiln Inlet gas analysis system is especially designed for the highest temperatures and dust loads in cement production. Typical applications are kiln inlet, riser duct, calciner and cyclone exit. Through this high temperature gas analysis system, compulsory data are collected for optimizing and controlling the combustion and the production process of a cement kiln. Process objectives The typical gasses to be measured in the kiln inlet are: Sustainable operation practice: Reduced greenhouse gasses Efficient utilisation of raw materials Safe production environment. Coaxial fiilter in heated Filter House Probe Sample End Burning balance (O 2, CO 2 ) Combustion conditions (CO, CH 4, Combustibles) Burning zone temperature changes (NO) Gas re-circulation and material build-ups (SO 2 ) Gas Sample 180 C One Pipe No Obstacles The investment in high temperature gas analysis equipment is very favourable with a typical pay-back time of below 200 days. The process benefits are: Reduced emission: Optimised combustion Use of alternative fuels Economically most beneficial production: Increased production Reduced fuel consumption Reduced clean-out of material build-ups in kiln Optimised clinker through-put and quality Fig. 2 During analysis, process gas is sampled through the 180 C heated ONE PIPE construction.

Maintenance and operation is easy with fast, full length probe inspection through the rear end access port.

3 Kiln Inlet and Calciner Gas Analysis - KilnLoq Equipment objectives The analysis equipment is placed right in the middle of a highly active and aggressive mineral calcination process. Based on our large process and operational experience in the cement industry, we have found three main equipment objectives that must be fulfilled if the equipment is to be successful: than previous available models due to heavy, special high temperature resistant stainless steel together with a multi layer construction. The probe is cooled by re-circulating cold water. Using cold water probe cooling gives up to 20% increased strength compared to hot cooling mediums like e.g. oil cooling, and water is also much safer in case of leakage. The probe gas sample path is electrically heated between C in a separate isolated and exchangeable inner pipe. Through this separation, the gas sampling and probe cooling is divided to ensure that no condensation will occur inside the probe. Due to its heavy construction, the probe is mounted in an Extraction Device for handling. In case of any operational problems, the Extraction Device will remove the probe from the process to a safe location. Automatic periodic probe extractions ensure that material build-ups on the probe are removed. An air blaster control is integrated in the system to remove any material build-up around the probe. Fig. 4 One of our very satisfied customers in front of the KilnLoq probe and analysing system which is made specially for the environment of a cement plant. The Extraction Device comes with full CE approved protection cover and operates with a safe, low temperature water cooling system. Simple - Easy Maintenance The design concept of the equipment involved is: keep it simple. A simple design is the most effective way of achieving simplicity in the maintenance and operation of the equipment. The modular system configuration and use of high quality but conventional components allow the equipment to be operated by non-specialists. The KilnLoq probe is introducing a truly revolutionary design to reduce the involved maintenance of the system. The design is based on the unique patent pending ONE PIPE layout of the entire sample path inside the probe inspired by the simplicity of an air blaster. No gas analysis probe can be made maintenance free, but the ONE PIPE design makes maintenance as easy as possible. A quick connector at the access port in the rear end of the probe gives access to the full length of the probe in seconds without any dismantling of the probe system or filter house. A full inspection or mechanical cleaning of the probe filter and sample pipe can be done in less than a couple of minutes. This feature is only possible through the One Pipe design as no obstacles like filter elements or pipe bends are found in the layout of the probe. Strong - Prevents Probe Bending The KilnLoq probe is strong - more than 8 times stronger Strong construction, cold water cooling, protection with the Extraction Device, and removal of raw material around the probe significantly increase the expected life time and actively prevent probe damages. Reliable - trouble-free operation The KilnLoq probe and the sampling system for the kiln inlet application is built with years of accumulated cement process know-how and gas analysis technology. The equipment control system and choice of components emphasise the Access Port Filter House ONE PIPE Fig. 5 A pro-active gas sample flow control feature prevents clogging of the probe by removing any obstacle in the sample pipe before it becomes a problem. The feature is based on a model of the pressure drop in the ONE PIPE sample line.

4 Kiln Inlet and Calciner Gas Analysis - KilnLoq need for practical solutions that are able to operate in the aggressive environment of a cement production process. All proven solutions from the previous version of high temperature analysis have been integrated into the KilnLoq model. As part of our continuous development, features capable of increasing the reliability and run-time of the equipment have been integrated. The heat input from the kiln process to the probe surface is monitored. This allows the system to determine if raw material is building up around the probe inside the kiln. If material builds up, it may become a hazard and cause damage to the probe, and the analysis will be effected by the entering of false air. With this unique heat input feature, information is provided to actively remove raw material and monitor the general status of material build-up in the kiln inlet area. Probe Cleaning Panel The reliability of the system has been significantly increased with the two added features. The first is achieved by the ONE PIPE design. By means of the PLC control system the sample pipe will be cleaned automatically at pre-set intervals. However, if any deviation from the normal probe pressure drop over time occurs, a signal will be generated by the PLC in order to start up preventive cleaning of the gas sample pipe. This feature removes any obstacles in the sample path before it becomes a problem. The second feature is a measurement of the heat input from the process to the probe surface. By measuring critical deviations in this heat input, it is possible to predict material buildup in the kiln inlet area around the probe. In this way, the gas analysis system is not only producing results from analysis of the gas composition in the kiln but is also providing information about general raw materials building up in the kiln inlet before they can be measured by any other devices. The Probe System Water Control Panel The probe is water cooled by a strong cooling jacket with re-circulating cold water from the Water Control Panel (WCP). Due to re-circulation of water, the consumption of water and lime is negligible. The cooling system works as a cold ON/OFF full flow system and needs no preheating or adjustments during operation. All operational status is monitored and refill of water is automatically done by a solenoid valve. In the probe, a separate and replaceable gas sample probe is electrically heated to C and inserted into the cooling jacket. A heated filter coaxial to the gas sample probe is part of the ONE PIPE probe layout. Due to this construction, the probe can be inspected and cleaned in its full length without dismantling or use of tools. The probe is cleaned by air at customer set intervals controlled by the GASloq 1200 cabinet. From the probe, the gas is sent to the GASloq 1200 cabinet for analysis through a 180 C heated sample hose. The Extraction Device is a handling and safety device for the KilnLoq probe. In case of any operational problems, the Extraction Device will remove the probe from the process. As the Extraction Device operates by two powerful air driven pistons, the large air receiver of the Probe Cleaning Panels serve as air supply back-up. The KilnLoq probe provides the best run-factor ever seen by any analysis system for high temperature analysis and is specially made for the cement industry. System configuration The system configuration comprises of four standard modules. They all come pre-tested and ready for installation with a minimum of commissioning time. System operation and components used are identical for all FLSmidth gas analysis applications, thus allowing easy training and a reduced number of needed spare parts. Only well-documented components that have proven their ability to handle very aggressive process gases are used. Material used for all parts in connection with gas is heated stainless steel, galvanised steel, PVDF or similar. The KilnLoq probe is a patent pending revolutionary extractive analysis method for the most troublesome process conditions on a cement plant. The probe has been specially designed for easy operation and maintenance based on a strong probe providing a high run-factor and reliability by the simplest design possible. Please contact us to learn how our kiln inlet gas analysis system will make you a more competitive cement producer.

5 Preheater Outlet Gas Analysis - DDOP GASloq 1200 Gas Preconditioning Unit (GMU) and analysis cabinet. Dual non cooled probe type DDOP for continuous analysis. One probe is sampling while the other is cleaned by purging air from the Probe Cleaning Panel (PCP). Air Power Fig. 6 The modular design is the basis of the plug and play installation. The system comes in 3 modules ready for installation on site: Dual Dry non Cooled Probe (type DDOP), Probe Cleaning Panel and GASloq preconditioning and analysis unit. Application The Preheater Outlet gas analysis system is especially designed and used as basis for interlocking of kiln burner, fan and electrical precipitators. When integrated into the FLSmidth technology, it can also be used for verifying various steps during kiln startup and shut down. The analysis at this point allows for final supervision of the burning and calcination process in the kiln system. Process objectives The key benefits of the equipment are: - True continuous gas analysis for real inter-locking safety - Low fuel consumption - Reduction of emission - Reduce fuel cost by burning waste Our equipment reflects this in the manner of operation and service. Our modular system layout makes it easy to operate. The Gas Monitoring Unit type GASloq 1200 is equipped with two parallel sampling systems supplying gas from each of the two probes and sending it to one common set of analyser units at high speed. During service of one probe, the other probe continues the analysis unaffected. The most beneficial analysis results are: Oxygen (O 2 ) for burning balance control. This measurement serves as a backup and reference analysis to the kiln inlet oxygen measurement. It also measures the level of false air entering the kiln and preheater system. Carbon Monoxide (CO) is high concentrations surveillance. The equipment is born with two extra alarm relay contacts for direct hot wire interlocking of e.g. an electrostatic precipitator. Methane (CH 4 ) is measured in connection with the use of natural gas as a combustible. The signal is used in the same manner as the CO analysis. Nitrogen Oxide (NO) is linked to the temperature development in the kiln burning zone. This measurement serves as a backup and reference analysis to the kiln inlet NO measurement. It can also be used if NO reducing measures are implemented into the kiln system as a controlling parameter. Sulphur Dioxides (SO 2 ) has been reduced at this measuring point compared to the kiln inlet. This analysis point is used to monitor the absorption of sulphur in the raw material. The measurement is most useful in the control and reduction of the SO 2 emission from the plant. It can also be used if SO 2 reducing measures are implemented into the kiln system as a controlling parameter. Equipment objectives Only a truly continuous gas analysis system can be used for the preheater gas measurement. Two probes shifts between each other during purging periods in order to extract gas for analysis at any time given to avoid blind periods which may cause potentially dangerous concentrations of process gas to pass the measuring undetected and thus cause explosions by the filter. As safety is the key issue, no compromise has been made. Even though extractive sampling technics are not the fastest possible measuring method, it offers the safest technique combining easily verified calibration and gas analysis together with true continuous gas sampling regardless of process conditions and possible dust contamination. The system only has to make one safety interlocking of the process to justify the investment. Running a cement plant without this equipment is simply not an option. Fig 7 Preheater Tower

6 Coal Mill Gas Analysis - Scan System Fig. 8 The analyser system comprises a Single Dry Filter Probe (SDFP) and/or a Single Dry Silo Probe (SDSP), a sample line and a GASloq gas conditioning system. The GASloq cabinet module takes care of the overall system control and operation. All the components for conditioning of the process gas as well as the analyser are placed in this module. Only well documented components that have proven their ability to handle very aggressive process gases are used. Application The coal mill gas analysis is used to avoid self-ignition and fires. Development of dangerous levels of CO are measured in coal filled silos if large amounts of coal dust is in storage or packed up. The system is built to measure CO by scanning between several silos. When a silo is empty, no analysis is needed. The O 2 measurement is used to check the operation of an inert operated coal mill. Since low oxygen process gas is used as flow media in the mill to suppress the combustion of the coal, continuous analysis of O 2 is very important. Process objectives The scan system at the coal mill is intended continuously to assist and notify the operator of conditions and give adequate warning of potential hazards at an early stage. Subsequent preventative action can then be made to secure the operation. Equipment objectives The analyser system comprises a combination of Single Dry Filter Probes (SDFP) and Single Dry Silo Probes (SDSP), sample lines and a GASloq gas conditioning system. The amount and type of probes is dependent on the actual number of measuring points. The GASloq cabinet module takes care of the overall system control and operation. A PLC system controls the functionality, performance and alarm handling of the system,and an HMI presents the present status and operation of the system. All the components Fig. 9 Coal Mill Silos for conditioning of the process gas as well as the analysers are placed in this module. Only well-documented components that have proven their ability to handle very aggressive process gases are used. The SDSP silo probe and the SDFP filter probe are able to operate in low temperatures and low dust conditions. The filter is placed inside the process providing gas analysis in process conditions. A Probe Cleaning Unit is not included as the dust content is very low. The coal mill department probes are made from corrosion resistant stainless steel. The filter probe can be installed at the exit of a bag house filter and will, when the filter is not in operation, monitor the development of CO originating from packed coal and thereby prevent self-ignition. During operation, the CO content can be monitored in the gas passing through the filter installation. The probe is used in connection with an inert operation of a coal mill and the measuring point must be analysing continuously for measuring the development of oxygen. The silo probe must be installed at the top of the silo in order to monitor the development of CO. The probe is made especially for pressure vessels. Used in a de-dusting cyclone, the analysing system only scans this measuring point if the process is not running and coal can be packed in the cyclone. Fire fighting equipment can be controlled from this analysis. Standard coal mill watch systems FLSmidth supplies different solutions from large multi scan analysis systems to small filter and silo watch systems. The silo and filter watch systems are small standard systems with limited possibilities in design and functionality. The multi scan systems are large multi point analysis systems for multiple silo and filter scanning. The multi scan systems can be designed for almost any kind of plant type and design.

7 GASloq Systems Gas Monitoring Unit GASloq 1200: The PLC control and gas conditioning equipment is placed in the GASloq 1200 cabinet. The GASloq 1200 system is designed to sample, condition and analyse process gas or emission gas and to present the measurement result in a display and/or to the plant control system. Extractive gas analysis means, contrary to in-situ gas analysis, that a sample is taken continuously from the process for analysis. The gas is sampled through a sample probe and a sample hose to the conditioning unit in the GASloq gas analysis system where the gas is conditioned and analysed. Operation and surveillance of system status, performance, alarm report, event report and calibration is conducted by a colour touchdisplay on the front of the cabinet. The user can easily adjust all relevant parameters of the system and check system performance. The 180 C hot gas received from the probe is cleaned by means of special aerosol filters. The gas is dried in a cooler. A peroxide dosing system can be enabled if the process gasses contain high levels of sulphur, as frequently seen in pet coke and waste fired kilns. Communication to the control room is made by hard-wire or through a serial connection offering all relevant system information. GASloq CUBE housing: A special housing GASloq CUBE can be supplied as a plug-andplay installation with ideal ambient installation conditions for the analysers. As an alternative to building an analyser shelter on site, the GASloq CUBE is a solution with obvious advantages. It provides large reductions in the overall installation cost and will also prove most beneficial in the pursuit of better run factor for the analysing equipment. This solution will reduce needed installation and commissioning time and provide the best possible conditions for service access. The GASloq CUBE cabinet samples, conditions and analyses process gas and presents the measurement to the plant control system. The CUBE is equipped with: Rittal cabinet for power compartment HMI colour touch display PLC type ABB or Siemens Analysers for e.g. O 2, CO, CH 4, NO X and SO 2 Gas sampling membrane pump, solenoid valves, flow valves and regulator Flow measurement and alarm Calibration control Room light and airconditioning. The inside of the shelter is pleasant and well organised. The ambient temperature is controlled by the airconditioning. Thus, the shelter provides an ideal working environment for both equipment and maintenance staff. All system components are selected on the basis of our process knowledge and have proven their abilities on site in respect of quality, ease of maintenance and resistance to corrosive gases. Comparing the cost on erecting a building locally, the overall project costs easily come out in favour of the GASloq CUBE. Utility equipment: Together with the GASloq gas analysis system, a wide range of accessories can be delivered. Calibration gases, parts for startup, wear and spare parts, commissioning and service contracts are among the most used accessories delivered together with a complete gas analysis solution.

8 CEM - Continuous Emission Monitoring Application During the last years, requirements for Continuos Emission Monitoring has increased significantly in order to fulfill the demands set by the local authorities. Due to an increasing number of demands on protection of the environment, most plants must now deal with even greater reductions on emission values and the reporting of these. On the other hand, plants are investing in CEM systems in order to burn waste, obtain ISO certification and introduce a Green Protection as a value driver. The benefits of the CEM system are Reduction of harmful emission gasses Reporting of emission values Reduction of fuel consumption through waste burning Income on disposal fees through waste burning Fulfilment of local emission legislation Legal specifications from local authorities set up requirements for the analytical components needed on various configurations. Typical approved analytical technics are specified together with a demand for e.g. sensitivity, availability, calibration and validation methods. Standardisation has been implemented in some countries/ regions; other areas have specified their own unique set of rules. Our large international experience allows us to choose a setup of instruments and measuring methods in compliance with every one of these rules and in this way provide the most beneficial solution. Our independency as supplier gives us the freedom to choose and implement the Best Available Technology (BAT). Being cement process specialists, we have Fig. 10 Emission monitoring system placed on stack the advantage of being able to combine the legal demands with production gains and hereby pursuit a plant emission strategy. Process objectives The CEM system installed in the stack measures both the concentration (in mg/m 3 or ppm) and the total emission of the various polluting gasses and dust. To report these data, a conversion to standardised physical values must be calculated in order to compare the data with emission limits set by the enforced emission legislation. As some of the components measured are very small in concentration, and the demand for precision set by legislation is very strict, the demands for high quality precision analysis with proven repeatability is obligatory. Two different technics are used to collect data: insitu and extractive. In-situ measurement is a method where the analyser is mounted directly on the stack, and the measurement is made in the stack. The measurement is made at actual process temperature, pressure, water content and dust concentrations. Thus, the meaurement system must be able to operate under these conditions, and the normalisation of the measurement must be done externally. Fig. 11 On site installation with dust, flow and gas analysers Extractive measurement is a method where process gas is extracted from the stack and transported to the gas analysis system. It is normally done in fixed physical conditions and is thus not affected by changing process conditions. It is able to handle high dust loads. To avoid wash out of gas components, a heated sample system is used. Validation and calibration can be done with a test gas allowing easy quality assurance of the equipment.

9 CEM - Continuous Emission Monitoring Sample probe for extractive gas analysis. In-situ measurement for dust, temperature and pressure In-situ gas analysis by LASER measurement principle In-situ ultra sonic flow measurement Gas Monitoring Unit GASloq 1200 or multi component analyser type FTIR Fig. 12 The configuration of the CEM equipment must reflect the legislation enforced by the local authorities or a specific permit for a given plant. Demands on CEM systems can be limited to a dust monitor or to a complex system comprising of dust, flow, pressure, temperature, gas analysis and data acquisition system. FLSmidth can provide the most beneficial solution as we are not dependent on any specific sub-supplier. Equipment objectives The choice of configuration type (in-situ or extractive) is very complex and is often determined by limitations in the legislation or by the given process conditions in the stack. FLSmidth s default configuration consists of a combination of the two techniques. For dust, flow, temperature and pressure, we normally use in-situ measurements. For gas analysis components, we use a heated extractive system. The reporting system must be in accordance with the legislation and able to produce the requested reports. Security of data is a major concern. FLSmidth is capable of supplying a stand-alone PC solution or a total integration into a plant central control system. ECS/StackGuide ECS/StackGuide is FLSmidth s cost-efficient product to guarantee all emission monitoring and reporting requirements in the cement and waste incineration industries. ECS/ StackGuide is a CEMS package with these main benefits: Guarantee for complete fulfilment of emission legislation requirements anywhere in the world Easy customisation to any special requirements for central, local or plant authorities Improving emission statistics by early warning of plant operators about any upcoming emission violation Gas components to be measured on the stack The measured components can be divided into groups, Requested Components (RC) as specified in the legislation and Utility Components (UC), which are needed to perform the conversion of data into normal values. Fig. 12 Continuous Emission and Monitoring (CEM) and reporting system. Optional incorporation with the ECS/ StackGuide system packages available for full plant integration and safety replication of data. Conventional fuels (coal, oil, gas etc.) Requested Components (RC): CO, NO X, SO 2, Dust Utility Components (UC): O 2, H 2 O, flow, temperature, pressure, calculation/ reporting Waste fuels Requested Components (RC): CO, NO X, SO 2, THC, HF, HCl Utility Components (UC): O 2, H 2 O, dust, flow, temperature, pressure and calculation/reporting For more information on the exact configuration of your emission reporting system, please contact any FLSmidth representative or visit our website

10 ECS/StackGuide - Emission Reporting ECS/StackGuide ECS/StackGuide is FLSmidth s cost-efficient product to guarantee all emission monitoring and reporting requirements. Combustion related plants such as cement and waste incinerations plants all over the world are facing a growing amount of rules and demands by various authorities on how to report their emissions from their production. The term CEMS (Continuous Emission Monitoring System) is applied for a complex of requirements for system configuration, monitoring roles, data validation methods and reporting types in the emission reporting demand. ECS/StackGuide is a CEMS package to accomplish these requirements. The main benefits of this package are: Guarantee for complete fulfilment of emission legislation requirements anywhere in the world Easy customisation to any special requirements for central, local or plant authorities Improvement of emission statistics by early warning of plant operators about any upcoming emission violation Cost-efficient solution If the raw data exists in ECS control systems, ECS/StackGuide supports the redundancy of the control system to collect the maximum available data from the servers. In addition, a catchup function in ECS/StackGuide makes sure that if the data collection is interrupted, the missing data will be collected automatically in order to avoid data gps in the CEMS database. Lack of data in the CEMS database may result in penalties. Real-time monitoring ECS/StackGuide can provide an environment in which the plant operators may monitor the current values of the emission. These values are not only the traditional raw values, but the normalised and validated values that are eventually going to affect the historical emission report in the historian part of the system. With configurable alarm limits, the operators will be able to take corrective actions in the process to minimise the emission violations. The real-time part of the system is a natural part of the ECS control system. However, it may also be integrated with other control systems as on-line imported and displayed data in the existing control system. Safe data storage All the retrieved raw data are kept intact. This means that the data validation of the raw values will only produce new data instead of deleting or manipulating the raw data. Keeping the raw data unchanged is not only crucial for the legislations, but also enables the user to simulate tighter emission requirements to forecast future investments in the process. The data storage media of ECS/StackGuide is the industrystandard MS-SQL database system. Traditionally, the CEMS solutions have been developed on a highly plant-specific basis. In order to meet the demands for data validation and monitoring roles, parts of the solutions have traditionally been implemented at the PLC level with programming intensive effort resulting in working, but quite complex solutions that are difficult to maintain in long-term. Other parts of the solution are traditionally implemented as special data retrieval and reporting system with customised programming approaches. ECS/StackGuide is the most professional and cost-efficient CEMS application with many advantages some of which are listed here: Secured data retrieval General features Historical databases and data access OPC data access Dedicated reporting package Built-in MS-Excel add-ins for report customisation Advanced trending software Data editing Web access Windows 2000, XP and 2003 Terminal server support for remote access Service release and hotfix support Realtime and historic emission control Store data for years Emission data MS-SQL Server relational database Advanced data validation methods Data tournament for dual ECS control system sources Catch up to retrieve lost data from down periods (by use of the ECS solution) Firewall between plant control and administrative system
