ABSTRACT:
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.
