Abstract
A reactor for forming crystals from soluble salts, which is capable of carrying out reaction and/or solvent extraction and/or crystallization, the reactor comprises an upper section 24 with a decanter comprising a vertical vessel with a horizontal weir 42 at the vessel s top and an outlet at the vessel s top for removing a light phase, a lower section 10 which is a crystallizer including a coaxial draft tube 12, at least one feed pipe 16, an agitator 14 located inside the draft tube, and one or more outlets 16 at the bottom for crystals slurry removal, and an intermediate section 26 including a coaxial vertical baffle 28, such that a gap between the draft tube and the coaxial vertical baffle can be adjusted by moving the vertical baffle up or down. A method for producing crystals using the apparatus is also disclosed.
