Until recently gas liquefication processeswe re characterised by the cascade method of refrigeration using the centrifugal compressor with expansion cycles for each separate gas component. But in recent years compression of a single, multi-component, refrigerant gas (MCR) had many advantages, not least that of using a compressor module of higher unit capacity. In today's large-scale LNG plants both types of compressor are used, and it is by the intelligent combination of both and the proper matching wit- the MCR process that the high output per liquefaction train is possible. Already shaft inputs exceed 100 000 hp and the technology developed for the process holds promise of inputs as great as 400 000 hp. This article records the thinking behind the recent installation of the world's largest MCR compressor installation at the LNG plant in Skikda, Algeria.
