新型硫转移剂在催化裂化装置上的工业应用

Commercial application of novel sulfur transfer additive in fluid catalytic cracking unit

在蓝星石油有限公司济南分公司催化裂化装置上进行新型RFS09烟气硫转移剂的工业应用。结果表明,在原料硫质量分数0.7%~0.9%和RFS09硫转移剂加注量5%情况下,再生烟气SO_2≤100 mg·m^(-3),达到环保法规要求,按空白SO_2浓度约1 200 mg·m^(-3)计算,再生烟气SO_2脱除率大于90%。RFS09硫转移剂试用期间,总液收和油浆收率等主要产物分布未出现异常变化,再生烟气粉尘浓度和油浆固含量保持稳定。

New RFS09 sulfur transfer additive is applied in FCC unit in Blue Star Petroleum （Jinan） Co.. The results show that,when Sulfur content in feedstock is 0.7% -0.9% and RFS09 added is 5% of fresh catalyst,SO2 in flue gas is lower than 100 mg· m-3, which can meet the requirement of specifica- tions. As the base SO2 emission is about 1 200 mg ·m-3, SO2 removal ratio is higher than 90%. During application of RFS09, main product distribution, including total liquid products and slurry yield, change little. Particle concentration in flue gas and solid content of slurry also remain constant.
