COMPRESSION TRAIN INCLUDING TWO CENTRIFUGAL COMPRESSORS AND LNG PLANT INCLUDING TWO CENTRIFUGAL COMPRESSORS

摘要

The compression train (200) comprises an engine (210), a first centrifugal compressor (220) driven by the engine (210) and a second centrifugal compressor (230) driven by the engine (210); the first centrifugal compressor (220) is housed inside one case; the second centrifugal compressor (230) is housed inside one case; the first centrifugal compressor (220) has a first inlet fluidly connected to a line of high molecular weight gas, in particular higher than 40; the second centrifugal compressor (230) has a second inlet fluidly connected to a line of low molecular weight gas, in particular between 20 and 30; the second centrifugal compressor (230) is arranged to provide a compression ratio higher than 10:1, preferably higher than 15:1.
