Abstract

System for nedkjøling av en fordampningstap-gasstrøm (BOG-gasstrøm) før komprimering i et fordampningstap-kondenseringsanlegg, omfattende en ledning (10) for mating av BOG til en kompressor (11; 11'') før varmeveksling med et lukket kjølesystem. Kjølesystemet omfatter kompressorer (2, 3, 4) og ekspandere (8, 9) samt et antall varmevekslere for varmeveksling med BOG-strømmen. Ekspanderene (8, 9) er innrettet i serie. En for-kjøler i tilførselsledningen (10) er i fluidforbindelse (32, 33) med nevnte lukkede kjølesystem, hvorved nevnte BOG for-kjøles i varmeveksling med en del av kjølemiddelet i det lukkede kjølesystem før nevnte komprimering.A system for cooling an evaporative loss gas stream (BOG gas stream) prior to compression in an evaporative loss condensing plant, comprising a line (10) for feeding BOG to a compressor (11; 11 '') before heat exchange with a closed cooling system. The cooling system includes compressors (2, 3, 4) and expanders (8, 9) as well as a number of heat exchangers for heat exchange with the BOG current. The expanders (8, 9) are arranged in series. A pre-cooler in the supply line (10) is in fluid communication (32, 33) with said closed cooling system, whereby said BOG is pre-cooled in heat exchange with a portion of the coolant in the closed cooling system before said compression.
