In this work, the crystallization of gypsum (CaSO 4 ·2H 2 O) in the temperature range of 20–60 °C is investigated along with the simultaneous regeneration of HCl by the reaction of concentrated CaCl 2 solution (3–3.5 M) with H 2 SO 4 at a concentration range of 2.6–8.0 M. Fast addition of H 2 SO 4 proved counter productive as it yielded a gel-like fine crystal suspension.
