(57) Abstract :
The invention concerns a method for separating a fraction (14) containing a supercritical or subcritical solvent (18) and a constituent
(16), the method including the following steps: diluting the fraction in a mixture comprising a constituent liquid phase (16) and a
solvent gas phase; separating the liquid phase by coalescing the liquid phase with a liquid eliminator (12). The method enables the
constituent and the solvent to be simply separated, thereby increasing the yield of the constituent and recycling the solvent. The
invention also concerns a device for separating such a fraction.
