Abstract

L'invention concerne un procédé de stockage et de transport de gaz naturel liquéfié (GNL) comprenant sensiblement de l'azote et du méthane, dans un réservoir (2) dans lequel on obtient une décoction du GNL. On extrait la décoction du réservoir (2) et on augmente la pression de la décoction, après quoi on refroidit ladite décoction dans un refroidisseur (20) à une température comprise entre la température de décoction du méthane et celle de l'azote. On ne renvoie dans le réservoir (2) que le méthane condensé. L'invention concerne également un dispositif de mise en oeuvre du procédé.
