ABSTRACT:
The object of the invention is to provide a method for preparing deep-frozen liquid gas for the purpose of recovering process energy for a downstream process, with which the refrigerating capacity of the deep-frozen liquid gas can also be used in the downstream process. According to the invention, this is achieved by the fact that the refrigerating capacity of the deep-frozen liquid gas (1) is fed as a heat sink to at least one of the part-steps of the downstream process via at least one heat-exchange medium (28, 54, 79) and, if said heat-exchange medium (28, 54, 79) is not available, the deep-frozen liquid gas (1) is regasified with an additional heat-exchange medium (32).
