LNG plant including two centrifugal compressors and a compression train 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, and the second centrifugal compressor (230) is housed inside one case, the first centrifugal compression The machine (220) has a first inlet in communication with a pipe of high molecular weight gas, in particular greater than 40, and the second centrifugal compressor (230), in particular, a low molecular weight gas between 20 and 30 And the second centrifugal compressor (230) is configured to provide a compression ratio higher than 10: 1, preferably higher than 15: 1.
