降低催化裂化烟气中SO_2排放的硫转移剂的工业应用

Industrial Application of Sulfur Transfer Additive for Reducing Sulfur Dioxide Emissions in FCC Flue Gas

介绍宝塔石化集团催化裂化装置使用的的无毒催化裂化烟气硫转移剂KHS-FCC进行工业试验的情况。结果表明,在原料油性质和装置操作条件基本不变的前提下,添加4%的硫转移剂,再生烟气中二氧化硫的质量浓度从350 mg/m3降至40 mg/m3,脱硫率保持在80%以上,并且硫转移剂的使用对催化裂化产物分布和产品的性质没有不利的影响。

The commercial trial of a nontoxic sulfur transfer additive KHS -FCC for reducing sulfur dioxide emissions in FCC flue gas using by Baota Petrochemical Group of catalytic cracking unit was introduced.The commercial trial of a nontoxic sulfur transfer additive KHS -FCC for reducing sulfur dioxide emissions in FCC flue gas using was carried out of catalytic cracking unit in Baota Petrochemical Group was introduced.Trial results showed that compared with base case under similar feeds tock properties and parameters , when the additive occupied 4% of the catalyst inventory , the SO2 content in regeneration flue gas dropped from 350 mg/m3 to 40 mg/m3 , keeping a sulfur removal rate of above 80%.At the same time , no significant negative and product properties was observed during the trial.
