Analysis of the Formation and Treatment of NOx in Catalytic Cracking Flue Gas
This article analyzes the reasons for the formation of NOx in the exhaust gas of an overlapping two-stage regeneration catalytic cracking unit.And combined with the catalytic cracking unit of a refinery in the south,three measures were proposed to treat nitrogen reduction,including crude oil processing,operation adjustment,and the use of additives.Finally,a comparison was made between the two types of denitration additives,and a more suitable additive for the denitration used in the refinery was determined.
