Calcium hydroxide from acetylene production used as chemical reagent
The acetylene manufacturing process uses water and calcium carbide as the primary materials, generating acetylene in the form of gas and a liquid solution of calcium hydroxide. Afterwards, this solution can be pressed in order to obtain a solid compost. Because of its composition, liquid or solid, it can be managed as a by-product in different production processes as a substitute for raw materials.
The liquid calcium hydroxide can be utilised for the neutralization of acidic waters, by coagulating for the generation of metallic oxides and for the stabilization of sludge in sewage treatment pl
