Abstract (en)
[origin: EP0874188A2] The deep-frozen liquid gas (1), before being used in the subsequent process is re-gasified in thermal exchange with at least one heat exchange medium (28,32). The refrigerating capacity of the deep-frozen gas as a heat sink is conveyed via a heat exchanger medium (28) at least to one of the part-steps in the process. In the case of unavailability of the heat exchanger medium, the deep-frozen liquid gas is re-gasified with an additional heat exchanger medium (32). The deep-frozen liquid gas is first divided into two part currents (30,33).
