06 Linde Engineering: Air separation LINEX TM air separation plants. LINEX TM air separation plants represent a new product line that transfers the benefits of the successful modular concept from the packaged air separation plant range to tonnage plant sizes. The benefit is significant economical advantages compared with fully tailor-made plants. LINEX TM air separation plants achieve very attractive on-stream times by combining substantially shorter equipment fabrication and delivery times with a flawless construction, commissioning and plant start-up. The process Not only the plant, but also the process is modular. As such, the various product splits and liquid requirements can be optimised. The process is based on all state-of-the-art air separation technologies, such as internal compression (IC) for GOX and GAN as well as highefficiency cryogenic rectification. Furthermore, options are available for split GOX pressure levels, cryogenic argon production and cryogenic rectification of other rare gases, such as krypton and xenon, as well as external compression to complement the internal compression. Of course, the requirements of the application are taken into consideration. A number of process options allow plant performance to be optimised with regards to requirement profiles as well as utility availability and cost. Power-saving measures and heat utilisation are important aspects in this cryogenic process. The superiority of this process is grounded on over 100 years of experience in air separation technology. Linde engineers have an in-depth understanding of the entire air separation process, and they are equipped with advanced engineering tools and methods for process design and optimisation. Linde-owned workshops worldwide fabricate proprietary equipment, which guarantees best performance in key process steps. And together with their main suppliers for rotary equipment, Linde has driven optimisation of key equipment. The company has built approx. 2,800 cryogenic air separation plants in more than 80 countries and has thereby dealt with different market requirements, ambient conditions and utility provisions. This is the basis for Linde s leading market position. Air filter Main air compressor Precooling unit Molecular sieve Booster air compressor M CW M Power CW M M M M Steam CW Power Power

08 Linde Engineering: Air separation Proprietary equipment. Linde s key proprietary equipment for air separation plants includes plate-fin heat exchangers, packings and columns as well as radial molecular adsorbers. These components can be manufactured in various Linde workshops worldwide. The in-house knowledge and experience in the manufacture of these essential plant components are the main contributing factors to the high plant efficiency regarding product purity and power consumption. Furthermore, this expertise is the basis for Linde s leading position in the air separation market. The project-specific engineering of these components is based on Linde s knowledge and design tools and ensures a reliable performance in all plant operating modes. What's more, Linde technology and equipment allows for best-in-class turn-down efficiencies.

Linde Engineering: Air separation 09 Plant reliability and availability. The Linde availability and reliability concept is based on the fully functional split of the air separation plant and the backup system, which together form the supply system. The entire system boasts reliability of very close to 100 percent. Such high reliability is economically realised by clever placement of redundant equipment throughout the plant, a meaningful selection of shelf spares and a reasonable sizing of backup storage. This critical design process is based on Linde s long-term operation experience utilising the recorded data for MTBF (mean time between failures), and MTTR (mean time to repair) and under consideration of the required reliability for the process in question. In addition, all key equipment as well as electrics, control and instrumentation is sourced from internationally renowned and Lindeapproved manufacturers. The focus is always on the highest quality and reliability available. Plant The plant encompasses all process, utility, electrical and other equipment associated with producing gaseous and liquid products. Backup system The backup system includes all equipment associated with storage and delivery of vaporised liquid to the pipeline customer. Supply system The supply system is the combination of the plant and the backup system. CAD view of a LINEX TM plant

10 Linde Engineering: Air separation Project execution. Low cost and short delivery time. The modular plant concept allows Linde to utilise its global network of workshops. Vast experience from the Linde packaged plant product line flows into the pre-fabrication of equipment. This expertise is coupled with first-rate site fabrication and erection based on many decades of involvement in a wide range of environments. The drivers for the definition of the projectspecific execution model are not only local labour cost, but also availability and quality aspects. Moreover, the start-up time can be positively influenced by pre-fabrication and pre-testing of key modules. Whatever plant execution model is selected, customers can be assured of state-of-the-art Linde technology approved and controlled by Linde s headquarters in Germany. And global procurement as well as global construction ensure that the execution phase also benefits from advantages inherent to the different local markets.

Linde Engineering: Air separation 11 Day-to-day performance. Plant operation The Linde operation concept allows full remote operation of the air separation plant with only limited site manning during short time periods. In addition, Linde offers global remote support through its own specialists. The state-of-the-art process control system is designed to support steadystate operation as well as smooth, remote changes between different operating modes. Highly sophisticated process control functions allow automatic load changes without operator interaction. The system can also deal with minor plant upsets and return the plant to stable operation. If during this time single products do not comply with specifications, supply is automatically switched from plant to backup. In case of more severe circumstances, the plant automatically switches to a safe condition, whilst the backup takes over the supply of all products without any operator interaction. Local operation personal is only required for plant start-up, routine checks and maintenance. Health, safety and environment The entire air separation plant is designed in accordance with international safety regulations and recommendations in regard to pressure vessels, cryogenic liquid and electrics (IEC, OSHA, EIGA, and CGA). Linde s own stringent safety standards are also integrated. This adherence to health and safety regulations coupled with our design philosophy ensures best-in-class protection of the health and safety of our employees as well as the surrounding environment. The process and its safety features are under continuous review, which is fuelled by Linde s ongoing operating experience. On top of that, our engineering, fabrication and execution processes are certified according to ISO 9000 and ISO 9001. Project-specific HAZOP studies ensure highest safety standards for every single plant. The highly efficient Linde components for heat transfer and air separation together with advanced rotary equipment from leading sub-vendors ensure low power and utility consumption. The very compact design of the plant reduces land requirements to a minimum. Control room of an air separation plant
