The Application And Research Of Technology In RFCCU Flue Gas Desulfurization And Denitrification

By the national environmental protection law is being more rigider gradually,removing and controlling discharge of industy RFCC pollutant such as sulfide,nitride is an important misson of our country's refineries who are faced with sustained development,American BELCO company has high tone and experience of controlling exhaust gas' pollutant blowoff all around the world In numerous desulfuration technology,wet desulfuration technics is using at most.In the side of RFCC gas desulfuration,American BELCO company's EDV is the most typical gas clean technology which is used in industry.EDV can be used alone,clean up SOX and dust efficiently,and also base on customers' concrete needs and investment,with other two technology to combine together to achieve revive gas cleaning up or denitration.This text mainly introduce American BELCO company's technical principle of EDV wet scrubbing,and this unit is used in Liaohe petrochemical corporation FCCU flue gas desulfurization and denitrification,combine with running condition,material consumption,and energy consumption of star-up and operation of this unit,propose a series of prioritization scheme,for raising this unit's desulfurization degree,reducing this unit's material consumption and energy consumption.By investment,process feasibility analysis,difficulty level of operation,economy and so on to select appropriate scheme,to be used in this unit.In denitrification side,Liaohe petrochemical corporation FCCU flue gas Ddesulfurization doesn't have method.By comparison to choose appropriate denitrification technology,add denitrification unit,and control gas cleaning attain locality and nation standard.
