Gas liquefaction and low-temperature gas separation are key features of a number of processes in the chemical process and utility industries. There are many processes, such as natural gas liquefaction and processing, industrial gas separation, and ethylene production that operate partially or totally below ambient temperature. Low temperature (sub-ambient) processes require heat rejection to refrigeration systems.
This course introduces to the technologies used in the design of the utility systems required for these processes, and provides insights and systematic approaches necessary for low-cost design solutions.
For large scale systems, multiple levels of refrigeration, cascaded systems, and mixed refrigerants are used. The large variation in potential structures, coupled with the integration of heat exchangers, and the implications of heat rejection from refrigeration, results in an extremely complex design task.
The operating costs for refrigeration systems are usually dominated by the cost of power to drive the compressors. Gas turbines, electric motors, and steam turbines can be employed to provide the mechanical power requirement.
Synthesis of such power systems is again complex, and requires integration with the refrigeration system in order to provide a cost effective solution.
The course concludes by examining the design complexities of utility design in natural gas liquefaction, ethylene, and gas separation.
Who Should Be Trained?
The course is intended for people with a chemical engineering background working in the petrochemical or chemical process industries where gas processing is carried out, or in engineering and consultancy companies servicing those industries. Process engineers with an interest in sub-ambient separation operations more efficient should attend this course.
