Modélisation d'une installation de concentration par évaporation avec compression mécanique de vapeur en présence de gaz incondensable

Abstract : The concentration by evaporation is a process able to treat many liquids until strong concentrations. Evaporation with mechanical vapor MVC compression is used for its energy flexibility and its profits. It makes it possible on the one hand to reduce the volume of the effluent in order to facilitate its transport or its final treatment, and on the other hand, the recovery of water contained in the effluent and its recycling. A major problem of the installations of MVC is the presence of incondensable gases in the evaporator. These gases are involved with the vapor in the compressor, and accumulate then on the walls of condensation, thus preventing a better heat exchange between the vapor and the product to be concentrated. The incondensable gas extraction is generally carried out at the end opposed to the vapor entry. Very often, The adjustment of the valve of purging of incondensable gases is manual. The best result is obtained by carrying out an optimal extraction further possible from the point of introduction from the vapor.
