FCC Flue Gas Desulfurization And Denitrification Processes Optimization

As countries to strengthen environmental regulation,all kinds of industrial waste gas emissions requirements to further improve the threshold,the oil refining industrial pollutants emission standards,make clear a regulation,July 1,2017,will perform the FCC flue gas SO₂ below 50 mg/m³,NO_X below 100 mg/m³ stricter standards,this to the enterprise the operation of the flue gas desulfurization denitration device is put forward higher requirements,from technology level also reversed transmission enterprise desulfurization denitration device modification or optimization,so as to realize the flue gas desulfurization denitration discharge standards for purifying flue gas emissions.Sinopec Qingdao petrochemical co.,LTD.（hereinafter referred to as"Qingdao petrochemical"）,in the aspect of environmental governance has always been at the forefront,positive response and to carry out the national environmental management requirements,on December 30,2014,the realization of FCC flue gas desulfurization denitration device of a drive to succeed,and achieving the flue gas emissions standards.Then the desulfurization denitration device running stability,in order to meet more stringent emission standards,the enterprise of the device for the small modification and operation optimization,realizing the maximization of the flue gas utilization,and the most stringent emission index.In April 2017,the enterprise fully utilized the existing conditions and carried out desulfurization optimization operation for the desulfurization and denitration device,realizing the extremely low emission of SO₂.At the same time,the enterprise has also carried out the process debugging of the matching denitrification device,verified the good effect of denitration technology and provided the treatment method for the catalytic cracking of the gas high NO_X condition.
