Title
(EN) METHOD IN THE UTILIZATION OF BOIL-OFF FROM LIQUID GAS AND APPARATUS FOR CARRYING OUT THE METHOD
(FR) PROCEDE D'UTILISATION DE GAZ EVAPORES PROVENANT DE GAZ LIQUIDES ET APPAREIL DE MISE EN OEUVRE DE CE PROCEDE
Abstract
(EN) In a plant for the production of fuel gas from boil-off and from liquefied gas with the aid of a combined heat exchanger (9), a compressor (4) is placed upstream of the heat exchanger in the gas line carrying boil-off. Compressed boil-off and liquefied gas pass in heat exchange in a combined heat exchanger (9) which has separate flow banks (7, 8) for liquefied gas and boil-off, respectively. From the combined heat exchanger (9), the two volumes of gas pass in a mixture to a consumer through a pipeline (5).
(FR) Cette invention concerne une installation destinée à la production de gaz combustibles à partir de gaz évaporés et de gaz liquéfiés, laquelle installation fait appel à un échangeur de chaleur combiné (9). Un compresseur (4) est placé en amont de l'échangeur de chaleur dans la conduite de gaz assurant le transport des gaz évaporés. Les gaz évaporés comprimés et les gaz liquéfiés passent par une étape d'échange thermique dans l'échangeur de chaleur combiné (9), lequel possède des rampes d'écoulement distinctes (7, 8) pour les gaz liquéfiés et les gaz évaporés, respectivement. A la sortie de l'échangeur de chaleur combiné (9), les deux volumes de gaz sont mélangés et envoyés au consommateur par l'intermédiaire d'un pipeline (5).
