A method of producing microparticles and nanoparticles of a solute via the extraction of solvent, having the solute dissolved therein, from an emulsion from source (114) using a supercritical fluid form source (112). The solute to be precipitated is dissolved in the solvent to form a solution, and the solution is dispersed in an immiscible or partially miscible liquid to form an emulsion at source (114). The particles are produced via the extraction of the solvent from the emulsion using the supercritical fluid in vessel (110). The process can produce an aqueous suspension of particles that are substantially insoluble in water, and the solvents used in the process to form the emulsion initially can be recovered and recycled from vessel ports (120) and (122).

L'invention concerne un procédé permettant de produire des microparticules et des nanoparticules d'un soluté par extraction d'un solvant dans lequel le soluté est dissous, d'une émulsion provenant d'une source (114) au moyen d'un fluide supercritique provenant d'une source (112). Le soluté devant être précipité est dissous dans le solvant de manière à former une solution, laquelle solution est dispersée dans un liquide non miscible ou partiellement miscible afin de former une émulsion à la source (114). Les particules sont produites grâce à l'extraction du solvant de l'émulsion au moyen du fluide supercritique dans une cuve (110). Le procédé décrit dans la présente invention peut permettre de produire une suspension aqueuse de particules qui sont essentiellement insolubles dans l'eau. Les solvants utilisés dans ce procédé pour former l'émulsion peuvent être, dés le départ, récupérés et recyclés depuis les ports (120) et (122) de la cuve.
