Abstract
A process for continuous dissolution of a solid in a reaction medium includes: (a) providing a liquid by withdrawal of a portion of the reaction medium from a first reaction vessel; (b) contacting the liquid provided in (a) with the solid in a second reaction vessel to form a solution of the solid; and (c) recycling the solution formed in step b) into the first reaction vessel. The solid in the second reaction vessel is present in the form of a fixed bed which is traversed by the liquid.
