In China, a number of power plants are installed with large imported FGD equipment. As from 1990s, China has built several demonstration projects with wet limestone-gypsum, simplified wet limestonegypsum, spray semi-drying, seawater, LIFAC and EBA processes along with vigorous introduction of foreign FGD equipment and technologies. As seen by FGD projects being under invitation for bid, large-sized units will generally be fitted with limestone-gypsum FGD equipment. Although theefficiency of FGD equipment is being raised rapidly, especially that of limestone/gypsum FGD equipment can reach 90%, such a technology has much room for improvement. In the coming ten years, China should exert itself to institute design and construction specification and standards, improve operation and maintenance techniques and develop new materials, etc.
