SHIP COMPRISING ENGINE Russian patent published in 2020 - IPC B63B25/16 B63H21/38 F17C6/00 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to shipbuilding and concerns a vessel with a stripping gas treatment system. Disclosed is a vessel with an engine, comprising: a first self-contained heat exchanger for heat exchange of stripping gas discharged from a storage container; multi-stage compressor for compression at several stages of stripping gas, which passed through the first independent heat exchanger after discharge from storage tank; a first decompressor for expanding a portion of stripping gas that has passed through the first self-contained heat exchanger after compression by the multistage compressor; a second decompressor for expanding another portion of stripping gas that has passed through the first self-contained heat exchanger after compression by the multistage compressor; and a second autonomous heat exchanger for heat exchange and cooling of a portion of stripping gas, which is compressed by the multistage compressor, using as a coolant a fluid medium which is expanded by the first decompressor, wherein first self-contained heat exchanger cools the other part of stripped gas compressed by multistage compressor using the stripping gas discharged from storage tank as coolant.

EFFECT: invention increases efficiency of repeated liquefaction of stripping gas.
