chemical equation during manufacturing process of gypsum

Flue-gas desulfurization - Wikipedia

The process by which this synthetic gypsum is created is also known as forced oxidation: CaSO 3(aq) + 2H 2 O (l) + ½O 2(g) → CaSO 4 · 2H 2 O (s) A natural alkaline usable to absorb SO 2 is seawater.

Cement Production - an overview | ScienceDirect Topics

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).
