Method for the liquefaction of a gas involving a thermo-acoustic cooling apparatus
The gas circulating in the conduit (1) is cooled and liquefied under pressure in the heat exchanger (11). The gas emanating from the heat exchanger (11) via the conduit (2) is guided by the conduit (3) into the expansion device (13). The gas is expanded until it reaches a pressure which is close to...

Summary: | The gas circulating in the conduit (1) is cooled and liquefied under pressure in the heat exchanger (11). The gas emanating from the heat exchanger (11) via the conduit (2) is guided by the conduit (3) into the expansion device (13). The gas is expanded until it reaches a pressure which is close to atmospheric pressure. The fluid discharged via the conduit (4) makes up the liquefied gas, e.g. liquefied natural gas. The refrigeration cycle consists of a refrigerating fluid which circulates inside the compressor (20), condenser (21), heat exchanger (11) and expansion device (229). According to the invention, a thermo-acoustic refrigeration apparatus cools the fluid obtained at the output of the heat exchanger (11) via the conduit (3), and a thermo-acoustic refrigeration apparatus (23) cools the fluid obtained at the output of the exchanger (11) via the conduit (24). |
