Abstract
(EN)
[Problem] To supply a liquefied gas production device which avoids complex routing of tubing and which can suppress increases in the space needed for installation. [Problem] In this liquefied gas production device for producing liquefied gas by liquefying a feed gas, a pipe rack unit 100, in which an air-cooled heat exchanger 101 is arranged, has a rectangular shape when seen from above. Along one long end of the pipe rack unit 100, a first compressor 4, a pre-cooling heat exchange unit 3, an auxiliary heat exchange unit 8 and a fourth compressor 9 are arranged in that order, and along the other long end of the pipe rack unit 100, a second compressor 6, a primary heat exchange unit 5, and a third compressor 7 are arranged in that order. Further, a pipe for the feed gas cooled by the pre-cooling heat exchange unit 4 crosses the pipe rack unit 100 and is connected to the primary heat exchange unit 5, and a pipe for the primary coolant compressed by the second and third compressors 6, 7 crosses the pipe rack unit 100 and is connected to the auxiliary heat exchange unit 8.

L'invention a pour objet la fourniture d'un dispositif de production de gaz liquéfié qui évite un routage complexe de tubes et qui peut supprimer les augmentations de l'espace nécessaire pour l'installation. Dans ce dispositif de production de gaz liquéfié pour la production de gaz liquéfié par liquéfaction d'un gaz d'alimentation, une unité de support de tuyaux 100, dans laquelle un échangeur de chaleur refroidi par air 101 est agencé, a une forme rectangulaire lorsqu'elle est vue de dessus. Le long d'une extrémité longue de l'unité de support de tuyaux 100, un premier compresseur 4, une unité d'échange de chaleur à refroidissement préalable 3, une unité d'échange de chaleur auxiliaire 8 et un quatrième compresseur 9 sont agencés dans cet ordre, et le long de l'autre extrémité longue de l'unité de support de tuyaux 100, un deuxième compresseur 6, une unité d'échange de chaleur primaire 5, et un troisième compresseur 7 sont agencés dans cet ordre. En outre, un tuyau pour le gaz d'alimentation refroidi par l'unité d'échange de chaleur à refroidissement préalable 4 croise l'unité de support de tuyaux 100 et est relié à l'unité d'échange de chaleur primaire 5, et un tuyau pour le liquide de refroidissement primaire comprimé par les deuxième et troisième compresseurs 6, 7 croise l'unité de support de tuyau 100 et est relié à l'unité d'échange de chaleur auxiliaire 8.
