REACTOR AND PROCESS FOR THE PRECIPITATION OF A SOLID PRODUCT

Abstract: The present invention relates to a reactor and to a relative process for the precipitation of a solid substance from a solution, in particular for a reactive pitcipitation or cwstallization. In particular, the invention relates to a reactive precipitation/ cwstallization reactor (l), comprising an outer tubular element (2) and an inner tubular element (3), coaxial With respect to the outer tubular element (2) along a longitudinal axis (X) of the reactor (l), so as to form, between an outer wall (3a) of the inner tubular element (3) and an inner wall (2a) of the outer tubular element (2), an annular channel (4), wherein the outer tubular element (2) comprises, at a first end (2 1), an inlet opening (5) for a first reactive fluid and, at a second end (2 an outlet opening (6) for a reaction mixture, and wherein the limer tubular element (3) comprises an inlet opening (7) for a second reactive fluid and, optionally , an outlet opening (8) for said second reactive fluid, and the inner tubular element (3) comprises, along the outer stilface (3a) thereof, a plurality of dispensing openings (9) for dispensing said second reactive fluid fed Into the inner tubular element (3).
