摘要:
The invention relates to a method for vaporising a cryogenic fluid, in particular liquefied natural gas that comprises the following steps: supplying heat from ambient air to a heat-transfer intermediate fluid in a first heat exchanger (3); supplying heat from said intermediate fluid to the cryogenic fluid in a second heat exchanger (5) in order to vaporise the cryogenic fluid. The intermediate fluid is fed into the second heat exchanger (5) after being compressed, and is fed into the first heat exchanger (3) after the expansion thereof in order to prevent rime formation.
摘要:
The method of vaporizing LNG consists in using previously dehumidified ambient air as a direct heat exchange fluid in a first air heat exchanger (5) for heating said LNG to a certain temperature. The dehumidification of the ambient air consists in reducing the temperature of the air in a second air heat exchanger (4) by direct heat exchange with said LNG previously heated in said first heat exchanger (5) at least to said certain temperature, said certain temperature lying approximately in the range −10° C. to −25° C.
