Title (EN) SYSTEM AND METHOD FOR TREATING GAS RESULTING FROM THE EVAPORATION OF A CRYOGENIC LIQUID
(FR) SYSTÈME ET PROCÉDÉ DE TRAITEMENT DE GAZ ISSU DE L'ÉVAPORATION D'UN LIQUIDE CRYOGÉNIQUE
Abstract:
(EN) The invention relates to a system comprising a power supply line for at least one motor, on which line a first unit (3) for compressing said gas is located, and a bypass to a return line on which cooling means (10) and reliquefaction means (30) are located in series. The cooling means comprise a second compression unit (11, 12, 13) and a heat exchanger (17) in series. Downstream of the second compression unit (11, 12, 13), a bypass to a loop (18, 20, 21) comprises first decompression means (14). The loop joins up with the return line upstream of the second compression unit (11, 12, 13) after passing through the heat exchanger (17) in the opposite direction to the gas fraction which has not been diverted by the loop.
(FR) Le système proposé comporte une ligne d'alimentation pour au moins un moteur sur laquelle se trouve une première unité de compression (3) dudit gaz et une dérivation vers une ligne de retour sur laquelle se trouvent successivement des moyens de refroidissement (10) et des moyens de reliquéfaction (30). Les moyens de refroidissement comportent successivement une seconde unité de compression (11, 12, 13) et un échangeur de chaleur (17). En aval de la seconde unité de compression (11, 12, 13) une dérivation vers une boucle (18, 20, 21) comporte de premiers moyens de détente (14), la boucle rejoignant la ligne de retour en amont de la seconde unité de compression (11, 12, 13) après avoir traversé l'échangeur (17) de chaleur à contresens par rapport à la fraction de gaz non dérivée par la boucle.
