METHOD AND DEVICE FOR SEPARATING GASES AND/OR LIQUIDS

摘要

Method and device for separating gases and/or liquids in a vertical column ( 1 ). The top product ( 4 ) of the column ( 1 ) is cooled and partly recycled. The bottom product ( 3 ) of the column ( 1 ) is heated and partly recycled. Cooling and heating take place with the aid of a thermoacoustic heat pump ( 10 ), which can be driven by external heating ( 2 ). A relatively large temperature difference between top product and bottom product can be overcome by this means.
