摘要: 为解决湿法脱硫塔蓝烟和烟气拖尾问题,在中国石化一套MIP-CGP装置上进行了增强型RFS硫转移剂的工业应用试验。助剂自2017年7月24日开始加注,在经过初始快速累积到系统藏量约1.5%,且于9月下旬按进料计剂耗约0.024 kg/t稳定加注时,进行了应用总结。结果表明,硫转移剂的应用对裂化产物分布、产品性质和装置运行无负面影响,可大幅降低烟气中SO2和SO3浓度,从而降低脱硫塔操作负荷和碱液消耗量,同时还可降低外排废水和循环液盐含量与COD,消除了蓝烟现象,显著改善了脱硫塔烟气拖尾情况。

Abstract: To resolve the problem of blue smoke and plume tailing from scrubber, a commercial trail of improved RFS SOx transfer additive was performed on a MIP-CGP unit of SINOPEC. After the initial rapid accumulation, the system storage is about 1.5% of catalyst inventory and then the additive is steadily added with rate of 0.024 kg/t based on fresh feed, the industrial application was summed up. The results showed that the application of RFS additive has little influence on product distribution, product properties and unit operation. SO2 and SO3 in flue gas is significantly decreased, therefore the consumption of NaOH solution is also decreased. Furthermore, TDS and COD in waste water and circulating water decline obviously. Blue smoke is diminished and plume tailing is well controlled.

Key words: FCC, flue gas, scrubber, plume, SOx transfer additive
