Wet Limestone-Gypsum Technology for Flue Gas Desulphurization (FGD)

The wet limestone-gypsum FGD process uses limestone or lime as reagent and consequently produces commercial grade gypsum. This system basically consists of a reagent preparation system, an absorber module, and a byproduct dewatering system.
Our technology represents the implementation of the latest design concept of a more efficient and compact system, which integrates SO2 removal, fly ash collection, in-situ forced oxidation and gypsum crystallization in one single reactor. This advanced system provides an excellent solution for our customers with prominent desulphurization efficiency, small land coverage, high reliability, good load following capability and low O&M cost.
