Conceptual Production Plant of Calcium Chloride from

2015-10-13  Granule, flake or powder calcium chloride could be produced through drying process. However, the technique and equipment use will determine which final product is generated. For example, to get powder calcium chloride the solution must be dried first and follow up with crushing process before the powder could be obtained while to obtain granule calcium chloride the solution only need to undergo drying process. Regardless the final product shape and size, the composition of calcium chloride should be the same at same purity. In terms of composition, according to product information sheet from OxyChem normal solid calcium chloride contain purity ranging from 77-87%. Table below shows the composition of granules calcium chloride

2019-9-29  Calcium chloride is produced in commercial amounts us-ing a variety of procedures: 1) refining of natural brines, typically with heating to increase concentration, 2) reac-tion of calcium hydroxide with ammonium chloride in Solvay soda ash production, and 3) reaction of hydrochlo-ric acid with calcium carbonate. The first two processes account for over 90% of the world’s total calcium chlo-ride production. Historically, natural brines sources are the dominant CaCl2 source.
