Abstract

Process and device for extracting and/or separating and/or preparing products in solution in a fluid in a supercritical state, according to which the physical conditions are varied to reduce the density and to isolate the dissolved products, the fluid being then returned to its initial state, characterised in that the solvent fluid is mixed with up to 10 % by weight of the total mixture of a second additive solvent, the process comprising, after the products have been isolated, a regeneration stage in which the mixture is brought into contact with an excess of additive under predetermined pressure and temperature conditions ensuring the readjustment of the composition of the mixture and its recycling. Application to supercritical phase chromatography and to extractions, separations and preparations using a supercritical fluid. <IMAGE>
