Innovation Technology Transformation of Tail Gas in Claus Sulfur Recovery Unit
The sulfur recovery unit of China Coal Pingshuo Energy and Chemical Co.,Ltd.in Shanxi adopts Dutch Hefeng technology,and the production process of"Claus unit+ammonia washing unit+acid concentration unit"is adopted for the first time in China.In view of the fact that this process can not meet the requirements of environmental protection under the new situation,innovative solutions are proposed to reduce sulfur dioxide emissions in tail gas through the transformation of the sulfur recovery system and the coupling of boiler ammonia desulfurization unit,providing innovative solutions for the design and transformation of environmental protection devices,and creating certain economic and environmental benefits.
