Abstract
La présente invention concerne un procédé de vidange d'un réservoir ayant contenu du gaz liquide, et une installation à cet effet. Après avoir vidangé la plus grande partie du contenu du réservoir, mais avec un reste de gaz sous forme vaporisée, on transfère le contenu résiduel aux fins d'échange de chaleur, directement ou indirectement, avec de l'azote froid. De l'azote est vaporisé et chauffé, puis transféré dans le réservoir, tandis que le gaz résiduel est refroidi et condensé, puis transféré dans un réservoir collecteur. L'installation comprend un système d'échangeurs de chaleur (4, 8; 30, 39) relié à l'arrivée (2) d'azote, et le gaz résiduel est chassé hors du réservoir à vidanges et envoyé à travers le système d'échange de chaleur (4, 8) afin de provoquer la vaporisation et le chauffage de l'azote à transférer dans le réservoir, de telle façon que le gaz résiduel qui en provient se condense. Une cuve de collecte (3) est branchée pour recevoir le gaz résiduel condensé. Afin d'empêcher que le gaz résiduel ne se gèle pendant l'échange de chaleur, on peut utiliser un agent réfrigérant qui provoque la vaporisation et le chauffage de l'azote, et l'employer aussi pour condenser le gaz résiduel sans refroidir ce dernier au-dessous de son point de congélation.
