摘要: 增强型RFS09硫转移剂可以有效地解决MIP富氧再生催化裂化装置再生烟气中SO3含量高形成的酸雾问题。RFS09增强型硫转移剂在中海油惠州石化有限公司的工业应用结果表明:在再生烟气过剩氧体积分数在4.2%~5.5%之间,硫转移剂加注到系统总藏量2.56%(w)时,再生烟气中SO3浓度由527.5 mg/m3下降到16.0 mg/m3,脱除率可达96.97%,有效地消除了外排烟气冒蓝烟和下坠等问题;SO2浓度由263.0 mg/m3降至14.0 mg/m3,脱除率可达94.67%;洗涤塔的碱耗降低90%以上。经综合经济效益核算,硫转移剂不仅可有效消除酸雾问题,同时不会增加装置运行成本。

Abstract: The sulfur transfer additive RFS09 was used in a 1.2 Mt/a FCCU (MIP) in CNOOC Huizhou Petrochemical Company. The application results showed that, at excessive oxygen content of 4.2%~5.5%, and when the accumulation amount of RFS09 reaches 2.56% of the catalyst inventory, the contents of SO3 and SO2 in the flue gas reduce from 527.5 mg/Nm3 and 263.0 mg/Nm3 to 16.0 mg/Nm3 and 14.0 mg/Nm3, respectively, the remove rate reaches 96.97% and 94.67% respectively. Meanwhile, the caustic consumption is decreased by over 90%. The cost accounting of benefit shows that, using the sulfur transfer agent to eliminate the acid mist will not increase the running cost of the company.

Key words: sulfur transfer additive, FCC flue gas, acid mist, SO3, economic benefit
