Description
Dry FGD process is a major FGD technology other than wet FGD process and has been widely used in China. In the last decade, it has been successfully applied not only to coal-fired power plants, but also to iron and steel sintering and pelleting plants, glass kilns, carbon black, aluminum, catalytic cracking, coking and other industry installations. In contrast to gypsum produced from wet FGD process, characteristics of dry FGD byproducts are often site-specific, depending on source flue gas compositions, unit operations, operating conditions, and other factors. These could affect dry FGD byproduct performance in utilization applications and generated products. Currently, over 30 million tons of dry FGD byproduct is produced annually in China. About 20 million tons is produced from various dry FGD units, built by Lonjing Environment Technology (Lonjing). In this paper, comprehensive characteristics, and utilization of dry FGD byproducts from these different sources will be discussed, including (1) physical and chemical property characterization and consistence, (2) commercial utilizations such as building materials, civil construction, mine application, and potential utilization such as filler for plastic and rubber etc. for evaluation. Also, the barriers and trends to dry FGD byproduct utilization will be discussed for comparison.
