Cryogenic air separation technology for gas liquification systems
Paper from the winner of the Institute of Refrigeration’s 2004 J&E Hall Gold Medal.
The need for cleaner burning fuels has caused an increase in demand for liquefied natural gas. It is essential therefore to develop liquefaction processes that are energy efficient and cost effective. This paper provides:
- a brief overview of the traditional natural gas liquefaction processes
- discussion of some state of the art processes
- the results of a new hybrid liquefaction processes.
This new process combines refrigeration methods commonly used in liquid nitrogen and liquid natural gas production. These results will highlight the optimum refrigeration methods for different temperature zones as gases are cooled from ambient temperature, liquefied, and subcooled.
