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

FIELD: shipbuilding.

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 second autonomous heat exchanger for pre-cooling the stripping gas compressed by the multi-stage compressor; first decompressor for expanding part of fluid medium, which is cooled by second autonomous heat exchanger and first self-contained heat exchanger; and a second decompressor for expansion of another portion of fluid medium, which is cooled by second autonomous heat exchanger and first self-contained heat exchanger, wherein the first self-contained heat exchanger cools the stripped gas which passed through the second self-contained heat exchanger after compression by the multi-stage compressor using the stripping gas discharged from the storage container, as coolant, and second autonomous heat exchanger cools the stripped gas, which is compressed by multistage compressor, using fluid medium expanded by first decompressor, as cooling agent.

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