摘要
本文分析了重叠两段再生催化裂化装置外排烟气中NOx的形成原因,并结合南方某炼油厂催化裂化装置,提出了采用原油加工、操作调整和运用助剂三种措施治理降氮.最后对两种脱硝助剂进行了比较,找到更适用于该炼油厂脱硝使用的助剂.
Abstract
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.
