<p>Device for separating at least one product such as a gas or solvent entrained in the vapour of a fluid, containing a vertical treatment chamber (2), in the upper part of the chamber means (3) of introducing the liquid to be treated and make it run down the length of the surfaces (4) offered by elements occupying part of the volume of the chamber and at the bottom of the chamber means (5) of introducing a transport vapour which moves towards the top of the chamber and means (6) of extracting the cleaned liquid. The surfaces along which the fluid flows are the internal surfaces of vertical tubes (7) called degassing tubes in a shell (8) into which is introduced heating vapour (9) with a temperature greater than the inlet temperature of the liquid, so that during the gravity displacement of the liquid, little bubbles of gas form which rise up the tubes in the opposite direction to the liquid and which can be extracted at the top of the chamber. Installation containing a separation device (as above) and an evaporator which also contains vertical tubes in a shell and into which is introduced a vapour (14) heating the external walls of the evaporation tubes.</p> |
