【Abstract】 The choice of process and equipment for ammonia desulphurization plants are discussed on the basis of engineering practice and production experience. The operational indexes of absorption solution suitable to various products are recommended. The principle of compact arrangement of the equipment is proposed to avoid build-up of crystal. It is suggested that ammonia source and product should be determined carefully, according to the economic respect and condition of gas to be treated.更多还原
