SYSTEM FOR TREATING GAS OBTAINED DURING CRYOGENIC LIQUID EVAPORATION, AND FEEDING COMPRESSED GAS INTO GAS ENGINE

摘要

FIELD: gas storage.;SUBSTANCE: system for treating gas obtained by evaporating cryogenic liquid and feeding compressed gas into gas engine includes, listed in flow direction, apparatus (10) for reliquefaction equipped with compression means (11, 12, 13), first heat exchanger (17) and throttling means (30). System also comprises a compressed gas feed pipeline, listed in the flow direction, having pump (48) for injecting fluid pressure and means (61) for evaporation under high pressure. Pipeline for compressed gas supply includes upstream relative to evaporation means (61) bypass pipeline (57) for supply of second heat exchanger (60) for heat exchange between, on one hand, compressed liquid transported via feed pipeline (56), and, on the other side, pipeline (22) of installation (10) for repeated liquefaction, located downstream relative to first heat exchanger and upstream relative to throttling means (30).;EFFECT: technical result consists in increasing the amount of repeatedly liquefied gas and reducing energy consumption.;13 cl, 8 dwg
