Abstract:

According to the reaction mechanism of limestone gypsum FGD process and the requirement for process water by FGD system, the feasibility of using the sea water as the main source of FGD process water was analyzed. The two schemes, the one is to use the sea water as main process water and another is to desalt the sea water and to use the desalted water as process water, were compared in technology and economical efficiency. The result can be used as reference in limestone gypsum FGD design.

Key words: lime-stone gypsum FGD process, source of process water, technical and economical comparison
