Burning catalyst is an important component unit in fluidized catalytic cracking (FCC) refining process. Coking flue gas is an important cause of SOx, NOx and particulate matter emissions in the refinery. It is an environmental problem to be solved in the refinery industry. This project aims to solve the problem of high SO3 content and strong abrasive property to catalytic in FCC flue gas: 1) explore the synergetic dust removal accompanied by catalytic reduction denitrification method based on filter-catalysis to reduce flue gas pre-denitrification in the condition of lean ammonia for reducing subsequent oxidation denitrification; 2) develop indirect ammonia new method based on the simultaneous desulfurization and denitrification of magnesium and ammonia for solving the problem of secondary ammonia pollution and reaching the goal of utilization of product; 3) explore gas phase oxidation of NOx and the reactive characteristic between the gas phase oxidation and gas-liquid absorption mass transfer; 4) develop new type of gas and liquid absorption mass transfer unit, realize high efficient absorption of SO2, NOx, and strengthen the capture of SO3; 5) explore condensation and separation unit based on acoustic-spin coupling principle to remove residual acid mist and fine particulate. Through this research, the mechanism of the key mass transfer and reaction process is clarified, the high efficient mass transfer and separation unit is developed, and the technology and application level of flue gas purification in the refinery are improved remarkably.
