摘要： 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 characterised 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.

摘要： The invention concerns a method for capturing very fine particles present in a fluid flux in liquid, gaseous or supercritical state and a device therefor. The method is characterised in that it comprises steps which consist in: causing said flux to pass through a filtering element (13); stopping the emission of said flux; countercurrent clearing of the filtering material (31) with a carbon dioxide flow under pressure, so as to drive the particles deposited on the filtering material (31); countercurrent expanding of the flux, so as to trap the particles within a solid carbon dioxide snow-type mixture formed during its expansion.

摘要： The invention concerns a device and a method for cleaning working parts, using a cleaning fluid, comprising a chamber (1) wherein is arranged a basket (7) containing the parts (27) to be cleaned, said basket (27) outer wall being spaced from the chamber (1) inner wall so as to provide between them a passage (9) for the cleaning fluid, the device further comprising intake means (25) for the cleaning fluid and means for extracting (15) it. Said device is characterised in that the chamber (1) base forms a ring-shaped chute (13) located beneath said passage (9), connected to the means extracting (15) the cleaning fluid, and inside which are arranged means for heating (17, 18) said fluid, and the intake means (25) are located in the chamber (1) upper part.

摘要： The invention concerns a method for collecting and encapsulating with a coating agent particles dispersed in a fluid at supercritical pressure and an installation for implementing said method. Said method is characterised in that it comprises steps which consist in: expanding said fluid at a pressure less than its critical pressure, so as to bring it to a gaseous state; causing said gas to trickle down in a liquid consisting of a solution substantially saturated with the coating agent in a solvent in which the particles are insoluble, so as to extract at least partially the solvent; and causing the coating agent to precipitate onto the particles thereby forming microcapsules.

摘要： This invention concerns a procedure for processing paper documents, including books. The procedure's characterizing feature is that it comprises an initial stage in which the documents to be processed are exposed to the effects of a supercritical pressure fluid formed from a mixture of a gas with 1 % to 20 % mass of an alcohol. The invention also concerns a solvent and equipment for applying the procedure.

摘要： The invention relates to a device for fractionating mixtures comprising separation elements which are series mounted and mounted in a closed loop. Said device is characterized in that the solvent used is a supercritical pressurized fluid, each of the separation elements is made of a membrane separation, it comprises means for injecting the solvent at a pressure which is greater than the critical pressure thereof and for maintaining the pressure in said loop at a value which is above critical pressure, and it further comprises means for injecting the diluent and for maintaining the pressure thereof at a value which is similar to the value of the pressure of the solvent (S) in each of the areas (I, II, III, IV).

摘要： The invention concerns a method for obtaining solid particles from at least a water soluble product, characterised in that it comprises steps which consist in: forming a solution of said product in an aqueous phase, producing an emulsion, or a micro-emulsion, consisting of said aqueous mixture and a polar organic phase, contacting said emulsion, or said micro-emulsion, with a fluid at supercritical pressure, or a liquefied gas, so that the latter extracts the organic phase and the water, thereby precipitating the formed solid particles of the water soluble product, and collecting the resulting formed particles.
