Abstract

The process and the apparatus serve for separation of a fluid mixture. The fluid mixture (1) is supplied to a pressure increase (2) in the liquid state at a first pressure (P1) which is subcritical and a first temperature (T1) which is subcritical. The pressure increase (2) involves bringing the fluid mixture to a second pressure (P2) which is supercritical without a phase transition. Under the second pressure (P2), it is heated (4) to a second temperature (T2) which is supercritical and then subjected to a decompression (7) to a third pressure (P3) which is subcritical. The decompressed fluid mixture (8) is finally supplied to a separation step (9) in which at least one component of the fluid mixture is removed, the separation step being performed at a third temperature (T3) which is subcritical.
