4 2 Membrane Technology Today membrane-based separation processes are state-of-theart and in some areas this technology has become the leading process solution. This was made possible by the development and continuous improvement of efficient and selective polymer membranes that ensure the thermal, chemical and mechanical stability necessary for industrial use. Integrating the membranes into suitable module designs ensure reliable and safe operation. Membranes are used in many applications in the chemical, petrochemical and oil/gas industries where liquid or gaseous mixtures containing hydrocarbons must be treated. This can serve recycling, emission protection or other operational requirements. One milestone on this way was the successful implementation of the gaspermeation process for selectively separating organic vapours from exhaust air, especially the treatment of vapours released during the distribution and storage of highly volatile hydrocarbons. Accompanied by related environmental protection legislation in the field of gasoline, a large number of membrane systems has been installed and successfully operated since 1988, making membrane technology today a leading technology in the field of industrial gasoline vapour recovery.

5 3 Membrane Technology Based on this experience, further gaspermeation applications were successfully implemented in recent years, for example, in the olefin industry. Today hundreds of industry-scale plants using BORSIG technology are successfully in operation. Besides gaspermeation BORSIG Membrane Technology entered a new challenging technology - the treatment of liquid hydrocarbons streams by the innovative organophilic nanofiltration process. For all these applications BORSIG Membrane Technology offers membranes and module types. Together with our partners and within the framework of R&D programmes, we are pursuing dedicated development efforts in order to continue offering our customers innovative and cost saving solutions in the future. BORSIG Membrane Technology offers: Stability tests and permeation measurements Targeted membrane screening and development Membranes, modules and membrane systems for gas separation Membranes and modules for organophilic nanofiltration Test modules and test systems Comprehensive process solutions

6 4 Emission Control Volatile Organic Compounds (VOC), defined as a large family of hydrocarbons with high volatility, occur naturally and are produced in many industrial processes. In a wide range of industrial applications, e.g. such as oil & gas industry, chemical industry and petrochemical industry the use of VOC leads to substantial emissions mainly caused by evaporation, displacement and purge procedures. These emissions of volatile organic compounds (VOC) can cause significant health risks, e.g. they are toxic and carcinogenic. Additionally they are known as precursor substances for ozone gas, causing summer smog and thereby contributing to global warming. In order to protect man and his environment, suitable measures must hence be taken in order to minimise the resultant emissions. The use, storage and distribution of solvents and petroleum products have been identified as the most significant sources for VOC emissions. Displacement and evaporation processes affect the release of organic vapours, which are in most cases mixed with air or other permanent gas. Typical products are Solvents All kind of gasoline Additives Diesel, jet fuel Alcohols Bio fuels Crude oil Worldwide corresponding regulations and emissions laws are implemented to drastically minimise the VOC emissions by the reduction of VOC consumption and by the installation of emission control systems. Parallel the industrial operators also focus on these topics to express their ecologically oriented production philosophy.

7 5 Emission Control Very often the installation of emission control systems goes along with economic benefits, e.g. when installing vapour recovery units to recover or liquefy the VOC vapours for reuse. The recovered product value or other associated effects can affect the profitability and return on investment (ROI). One example is the tax-refund, which will be granted in some countries, when the vapours of already taxed products are recovered and returned into the distribution chain. BORSIG Membrane Technology offers emission control solutions with maximum recovery rates of up to 99.9% and thereby enables compliance with all customary emission standards worldwide whilst also fulfilling the highest quality, safety and reliability demands. BORSIG Membrane Technology's portfolio in the field of emissions protection includes: BORSIG Vapour Recovery Unit (VRU) VOC control for tank farms, marine loading and refineries BORSIG Carbon Retrofit Unit (CRU) Retrofit of existing active carbon based recovery system BORSIG Vent Recovery System (VRS) Product loss reduction at retail stations

8 6 Emission Control BORSIG Vapour Recovery Unit VOC control for tank farms, marine loading and refineries The Application During storage and distribution of petroleum products large streams of vapours are released by evaporation and displacement procedures, e.g. by truck-, railcar- or ship loading applications. According to the common emission legislations and technical guidelines these vapours must be treated preferably in vapour recovery units. Typical products include: Gasoline (all grades) ETBE, MTBE, all kind of additives Diesel, jet fuel Intermediate products, e.g. reformate, naphtha etc. Ethanol, methanol Chemicals, solvents Due to the high volatility and therefore high concentration of the vapours a substantial product loss is affected and also corresponding strict emission limits have been defined to avoid the emission of these harmful substances, e.g. European Directive 94/EC/63 German TA-Luft and BImSchG Swiss LRV US EPA Modern vapour recovery units must fulfil all these latest requirements as well as further options to allow a flexible and most economical operation: Fulfil highest safety demands to process explosive vapours Recovery of pure product vapours but also of mixed products vapours Considering the pre-loading of vessels and railcars Treatment of conventional gasoline vapours Compatibility with new gasoline specifications, e.g. Ethanol 85, bio fuels Highest flexibility regarding future expansion of customer s product portfolio or changing specifications

9 7 Emission Control BORSIG Vapour Recovery Unit The BORSIG Solution The BORSIG Vapour Recovery Unit (VRU) is based on a combination of absorption or condensation and membrane separation. Main equipment are liquid ring compressor, scrubber, membrane separation stage and vacuum pump. The BORSIG VRU process enables an effective treatment of the vapours meeting the required emission level. The vapour/air mixture is taken into the VRU by the liquid ring compressor and is mixed with the membrane recycle stream. The compressor compresses the mixture to the required discharge pressure using a part of the absorbent stream as liquid hydrocarbon seal that creates a noncontact seal ring and removes the heat of compression from the gas stream. The compressed gas is discharged together with the ring liquid into the absorption column, where vapours get into contact with the external absorbent flow and the liquefaction of the vapours is effected by condensation and absorption effects. The non-liquefied vapour stream leaves the column at the top and enters the membrane separation modules. Supported by the vacuum pump the membrane stage enables a final cleaning of the vapour stream and the separated enriched hydrocarbon vapours are recycled to the compressor inlet, which enables an inherent safety principle by enrichment of the VRU inlet stream. Further vapour cleaning can also be achieved by additional polishing stages. BORSIG VRUs are equipped with high quality machinery and materials only. The combination with most reliable instrumentation and latest stateof-the-art control systems makes it suitable for all applications and products. Advantages & Benefits Most compact and modular design Unique inherent safety principle High efficiency of recovery Customised to meet individual applications Considering customer s codes & standards Flexible and safe for all products Flexible for emission changes due to modular process design Low maintenance due to machinery and material selection (e.g. use of stainless steel) Highest reliability due to high quality equipment and control Self-in-taking principle enables minimised costs for customer s vapour piping

10 8 Emission Control BORSIG Carbon Retrofit Unit Retrofit of existing active carbon based recovery system The Application In existing vapour recovery units based on active carbon adsorption technology the adsorbers are designed for a maximum mass flow of hydrocarbons before being desorbed again. Practical experience has shown that operators are facing frequently the following difficulties: Customer needs more capacity, e.g. due to increased transshipment The performance of the existing unit is not efficient enough to meet the required emission level New product vapours have negative impact on the active carbon or cannot be adsorbed and must be separated before entering the adsorbers Safety risks related to potential dangerous exothermic reactions shall be prevented. The BORSIG Solution The Carbon Retrofit Unit significantly reduces the hydrocarbon concentration and mass flow entering the adsorbers. The separated enriched stream is bypassing the adsorbers and directly entering the existing absorption system (scrubber). This enables adsorber performance increase and debottlenecking. The Carbon Retrofit Unit is installed upstream the existing active carbon system. The vapour stream is separated by the membrane unit into two streams. The stream passing through the membrane material is highly enriched with hydrocarbons and is given directly into the existing scrubber part of the carbon unit, where the hydrocarbons are liquefied. The light stream is entering the existing adsorbers. The integration of the Carbon Retrofit Unit is easy and cost effective with only minor modifications of the existing active-carbon-based vapour recovery unit. The retrofit system mainly consists of the membrane unit, a vacuum pump and an optional blower. Advantages and Benefits Tremendous reduction of hydrocarbon mass flow to the carbon beds Increased safety of the carbon VRU due to the reduction of exothermic reactions in the carbon beds Substantial increase of the capacity of the retrofitted system Increased efficiency and lower emission level Pre-assembled skid-mounted design Easy implementation Low maintenance Reduced specific power consumption

12 10 Emission Control BORSIG Vent Recovery System Product loss reduction at retail stations The Application On car filling stations three main sources for VOC emissions are identified: Emissions caused by storage tank filling Typically these emissions can be minimised by so-called Stage I measures, by balancing the vapours released during the filling between the underground storage tank and the filling truck. Emissions caused by car tank filling The emissions caused by released vapours from car tank can be reduced by a conventional Stage II vapour return to the storage tank enabled by vapour suction integrated in the filling nozzle. Sometimes a limited efficiency of vapour collection affects the suction of air into the storage tank and therefore leads to further evaporation of the storage product. Storage Tank Breathing Temperature affected breathing and vaporisation in the storage tank leads to increased tank pressure and therefore to vent stack emissions to the atmosphere.

13 11 Emission Control BORSIG Vent Recovery System Nowadays more and more local regulations require the control of the entire sealing of car filling stations and the reduction of corresponding leakage losses, which can cause a product loss (wet stock loss) of up to 0,5% of the car filling stations throughput and sometimes more. Furthermore these losses have an impact on our environment as well as on the safety in operating car filling stations, while hazardous products and the vapours are handled and emitted. The BORSIG Solution BORSIG Membrane Technology developed an innovative enhanced add-on system enabling the increase of the vapour return ratio from the car nozzle to the storage tank for more efficient vapour collection. The BORSIG VRS is connected to the vent stack to treat the vented air/gasoline vapours. Proven membrane technology generates two streams and selectively separates the air from the hydrocarbon molecules. The valuable gasoline fraction is returned to the storage to keep the gas phase saturated and even to liquefy the gasoline vapours when the due point is reached. The cleaned air is released to the atmosphere. Advantages and Benefits Proven reduction of wet stock losses by 95%, measured by third party Increased safety of car filling stations Better prospects of obtaining planning permission from the authorities and improved neighbourhood acceptance for filling stations Reduced exposure of customers to hydrocarbon vapours during car fuelling. Substantial pay back related to the yearly gasoline throughput Improved marketing image of the operator Elimination of direct stack emission Monitoring of the car filling station tightness and function

14 12 Product Recovery Product recovery systems must meet with evermore demanding efficiency requirements. Economic efficiency, productivity, improved sustainability of technological processes, as well as optimum utilisation of our resources are key challenges in this for the industry. BORSIG Membrane Technology offers optimum solutions here which helps minimising losses, to recover valuable raw materials or products from exhaust air or process gas flows and their recycling into the production process and therefore enables: - Recovery of valuable feedstock and product - Significant reduction of waste and flare gas capacities Important products and applications include: Ethylene monomer from polyethylene (HDPE, LDPE, etc.), EO or VAM productions Propylene monomer from polypropylene production Solvent (Butane, Hexane etc.) from slurry-type polymer production processes Vinyl chloride monomer (VCM) from PVC production Aromatics (Benzene, Toluene, Xylene etc.) from production and storage MTBE, ETBE Fluoro & Chloro Hydrocarbons from any related processes Methanol, Ethanol Bio-Fuels from production & storage Our products include: BORSIG Ethylene Recovery Unit Ethylene monomer recovery for polyethylene (PE), ethylene oxide (EO) production BORSIG Propylene Recovery Unit Propylene monomer recovery for polypropylene (PP) production BORSIG Hydrocarbon Recovery Unit Recovery of valuable hydrocarbon products

15 13 Product Recovery BORSIG Ethylene Recovery Unit Ethylene recovery for production of polyethylene (PE) and production of ethylene oxide (EO) and vinyl acetate monomer (VAM) The Application During the production of polyethylene (PE) one typical process step is the degassing of PE powder and downstream pressure condensation to condensate hydrocarbons. The residual purge gas stream is still rich on non-condensable hydrocarbons and monomer. To prevent enrichment of inert gas a side stream is typically sent to the flare and also effects a loss of monomer and hydrocarbons. Similar purge gas streams can be identified in vinyl acetate monomer (VAM) and ethylene oxide (EO) processes. For example the inert gas Argon must be purged out of the process to prevent enrichment. Furthermore internal distillation overhead vents and other reactor purges can be treated. All these procedure effect - substantial loss of ethylene monomer and of other solvents - increased flare gas streams and therefore secondary emissions to the atmosphere The BORSIG Solution The BORSIG Ethylene Recovery technology is an easy add-on system and can be considered in existing and new process installations. The purge gas stream, typically pressurized and containing the ethylene monomer and disturbing inert gas, is fed into the membrane system, while the permeate side of the membrane separation stage is fed back to the existing process gas compressor s suction side. By means of the resulting pressure difference and the hydrocarbon selective membrane material, the purge gas stream is separated into the inert gas enriched off gas and the recycled ethylene-rich permeate stream. Typically no other equipment or machinery is required, which results in a very simple and reliable process solution. Advantages & Benefits Easy installation in new plants and easy retrofit of existing systems Easiest solution Key equipment membrane separator only Quick installation and easy implementation by skid-mounted modular design Very short payback period Low maintenance Safe and reliable operation Tailor-made design to meet customer s codes and specifications

16 14 Product Recovery BORSIG Propylene Recovery Unit Propylene recovery for production of polypropylene (PP) The Application During the production of polypropylene (PP) one typical process step is the degassing of PP resin in the resin bin in order to purge out non-reacted propylene monomer. Typically nitrogen is used and continuous purge streams containing substantial content of monomer have to processed to minimise the loss of profit and the required flare gas capacities: - Substantial loss of propylene monomer - Increased flare gas streams and therefore secondary emissions to the atmosphere The BORSIG Solution The BORSIG Propylene Recovery technology is an easy add-on system and can be considered in existing and new process installations. The purge gas stream compressed and condensed in the downstream condenser stage, which might be cooled with cooling agent or liquid propylene. For some PP production licenses an additional dryer system must be installed prior to condensation. After separating the condensate the remaining purge gas is fed into the membrane system, while the permeate side of the membrane separation stage is fed back to compressor s suction side. By means of the resulting pressure difference and the hydrocarbon selective membrane material, the purge gas stream is separated into the purified nitrogen stream and the recycled propylene-rich permeate stream. A small part of the separated stream is sent to the flare to prevent accumulation of lighter components. The process system consists beside the required membrane stage, mainly of compressor and condensation unit, fully designed as package unit with dedicated PLC. Sometimes dryers and transfer liquid pumps are installed to meet specific client s requirements. Advantages & Benefits Recovery rates > 95% Propylene and purity > 99 mol.% Nitrogen Short payback periods in order of 1-3 years Safe operation, high reliability, low maintenance Tailor-made design to specific plant s conditions and local regulations Quick installation and easy implementation through package unit design Feasibility for adaption into existing plants (retrofit design)

17 15 Product Recovery BORSIG Hydrocarbon Recovery Unit Recovery of valuable hydrocarbon products The Application In many petrochemical/chemical productions process streams are generated containing significant amounts of hydrocarbons, such as solvents, alcohols, aromatics etc. Typically these hydrocarbons are mixed in inert gas streams and must be treated in order to meet following typical targets: - to meet off-gas conditions according to emission legislations - to recover the valuable hydrocarbon content and therefore minimise the loss of product and profit - to meet the inlet conditions of any downstream process steps and systems The BORSIG Solution The BORSIG Hydrocarbon Recovery technology is a portfolio of specially developed and customised process solution to meet the targets. Typically the membrane separation is combined with other unit operations, such as absorption, condensation, extraction etc. These hybrid processes are very efficient and enable the customer to operate his process with highest economically and ecologically efficiency. A typical application is the powder degassing in slurry-type PE plants. Polymer is flashed and stripped with hot nitrogen and the released purge gas existing of nitrogen and solvents like butane, pentane or hexane can be processed by a sophisticated BORSIG Hydrocarbon Recovery process. The liquefied solvent and the nitrogen can be provided for reuse with highest purity. Advantages & Benefits Flexible system for multiple components handling Highest product purities Stand-alone solution possible Moderate pressures and temperatures applied for required condensation Safe operation, high reliability, low maintenance Modular design to meet specific plant s conditions and local regulations Quick installation and easy implementation by package unit design Feasibility for adoption to existing plants (retrofit design)

18 16 Gas Conditioning BORSIG Membrane Technology offers the possibility to treat gas flows in oil and gas production applications. The aim is to condition raw gas flows or to improve product quality to comply with customer s gas specifications, pipeline specifications or calorific-value requirements. The required gas quality is typically specified by defining methane content, pressure dew points, calorific values or a minimum methane number. These quality parameters are typically determined by the share of higher hydrocarbons (C3+), CO2 or O2 in the gas. The possibilities offered by BORSIG Membrane Technology at a glance: BORSIG Fuel Gas Conditioning Gas treatment for pipeline, gas engine and turbine applications BORSIG Oxygen Enrichment Oxygen enrichment for combustion processes BORSIG Gas Separation Bulk separation of gas stream BORSIG Biogas Processing Membranes and systems for biogas treatment Process concepts in addition or as an alternative to conventional process solutions.

19 17 Gas Conditioning BORSIG Fuel Gas Conditioning Gas treatment for pipeline, gas engine and turbine applications Fuel gas taken from the sources available at site and in particular in remote production locations often does not meet the high quality standards required for pipeline injection or for utilisation in modern high efficiency gas turbines or engines. The Application The fuel gas quality is typically specified in terms of minimum methane content, methane number, dew point or calorific value or other closely related parameters. All these parameters are determined by the content of higher hydrocarbons in the fuel gas. Hence in order to increase the fuel gas quality with respect to these parameters a selective removal or significant reduction of the content of these C3+ components is desired. The BORSIG Solution The BORSIG membrane technology for hydrocarbon separation provides a simple, cost saving and highly reliable solution for fuel gas upgrading and calorific value control. The raw gas is taken directly out of a high pressure line at site or compressed by a separate compressor and routed to the membrane unit. The heavier hydrocarbons (C3+) are separated preferentially and are concentrated on the low pressure side of the membrane, whereas the lighter components, mainly the methane and ethane, remain at high pressure. This lean residue of the membrane provides the high quality fuel gas to be utilised in the gas motor or turbine or to be injected into a respective pipeline. The enriched permeate stream is routed to a low pressure line at site or typically recycled to the compressor suction. Because the membrane provides also a separation capability for water the membrane will also allow a certain degree of dehydration simultaneously with the hydrocarbon separation. This may be sufficient to achieve the required water dewpoint specification and to reduce the risk of hydrate formation. Advantages & Benefits High C3+ removal High equipment reliability and on-stream availability Completely assembled compact process units Easy integration into existing facilities Minimum of supervision and maintenance Prolonged life time of gas turbines or engines and related components Particularly suitable for offshore applications and remote locations

20 18 Gas Conditioning BORSIG Oxygen Enrichment BORSIG Gas Separation Oxygen enrichment for combustion processes Various processes requiring oxygen are just being fed with air. Typically higher process efficiency or product yields can be achieved when operating these processes with a gas stream with higher oxygen content than provided by ambient air. The BORSIG membrane technology provides an attractive solution to generate oxygen enriched feed gas streams utilised for instance in combustion or chemical process applications. Bulk separation of gas stream CO2 SEPARATION CO2 gas separation applications are found within a wide range of operating pressures and feed gas compositions. Typically in dependence on the actual application also the requirements regarding product purity and separation efficiency do vary within a wide range. Main applications are for instance biogas and natural gas treatment or more general CO2 separation/recovery from process off gas streams. The membrane technology provides efficient and cost effective solutions for CO2 separation in a wide range of these applications. Natural Gas Treatment Nowadays a significantly increased percentage of worldwide gas production is dealing with natural gas containing considerable amounts of CO2. A typical CO2 content is within the range of 5 to 15 %. In order to maintain the gas quality and to meet pipeline specification requirements efficient and economically viable CO2 separation technologies have to be applied. For a wide range of applications in particular for small and medium gas flow rates the membrane technology can provide interesting process concepts in addition or as an alternative to conventional process solutions.

21 19 Gas Conditioning BORSIG Biogas Processing grade Product Gas Bio-Methane CO2/ methane separation Membrane Unit Lean Off-gas Utilisation / Treatment Network Operator Compression, meetering, odoration etc Gas Network Membranes and systems for biogas treatment With the recently increasing efforts to utilise renewable energy sources biogas is considered to be one of the major options for providing a significant share in the modern energy mix. To use this source the produced raw-biogas is processed and treated in order to meet the gas specifications required for utilisation. The Application A raw-biogas generated by fermentation contains methane (typically 50 to 60 %) and CO2. In order to utilise the bio-methane for the injection in the gas distribution network or as fuel gas for motors or turbines for energy production the raw biogas is treated and upgraded accordingly. The BORSIG Solution The BORSIG membrane and process technology enables an efficient CO2/methane separation process to provide the product gas at the required purity while reducing the loss of methane. The biogas treatment process set-up comprises Filter/coalescer for free water removal Desulphurisation if required to meet respective pipeline specifications of network operator Gas compression Membrane separation Product gas metering and conditioning (odoration, etc.) to be provided by network operator Advantages & Benefits Reduced scope of equipment, reduced size and weight Minimum mechanical complexity: Static system / no moving parts / easy to operate No additional chemicals or refrigerants required Flexible modular design Completely prefabricated containerised solution ready for installation and operation These advantages allow attractive process solutions for biogas processing already for operators of biogas plants within the lower capacity range.
