The invention concerns a method and an installation for setting in adsorbed
state, on a porous support, compounds contained in a product comprising a
first step which consists in extracting the compounds by contacting the
product with at least a solvent at supercritical pressure to obtain a
mixture of extracts and solvent. The method is characterized in that it
comprises a second step which consists in eliminating the water contained
in the mixture of extracts and solvent, adjusting the temperature and
pressure conditions so as to obtain, a first phase consisting of solvent
in gaseous state and a second phase consisting of a mixture of liquids
formed of solvent and extracts of the products; causing said two phases to
trickle through a porous support adapted to adsorb the extracts;
vaporizing the solvent contained in the second phase.
