新型硫转移剂在不完全再生催化裂化装置上的工业应用

COMMERCIAL APPLICATION OF SULFUR TRANSFER ADDITIVE ON PARTIAL COMBUSTION FCC UNIT

在中国石油广西石化公司不完全再生催化裂化装置上进行了新型RFS09硫转移剂的工业应用。结果表明:在原料硫质量分数平均值为0.338%、RFS09加注量为5%的情况下,CO锅炉出口烟气中SO_2浓度不大于850mg/m^3,达到预订技术指标要求;按空白SO_2浓度约1 800mg/m^3计算,再生烟气SO_2脱除率达到50%以上。此外,新型RFS09硫转移剂试用期间,装置总液体收率、油浆收率和焦炭产率基本不变;再生烟气粉尘浓度基本稳定且略有下降,油浆固含量保持稳定。

The new generation sulfur transfer additive RFS09 was applied on the partial combustion FCC unit in PetroChina Guangxi Petrochemical Company. The results show that when the average sulfur content in feedstock is 0. 338% and RFS09 is added at 5% of the fresh catalyst,SO2 in the flue gas from CO boiler is less than 850 mg/m^3 ,which meets the requirment of specifications. The SO2 removal rate is higher than 50% ,calculated based on the SO2 emission about 1 800 mg/m^3 without additive. In addition, during the trail of RFS09, the yields of total liquid products, slurry and coke change little. The particle concentration in flue gas remains constant and even decreases sightly, and solid content of slurry also remains constant.
