增强型RFS09硫转移剂在催化裂化装置的工业应用

INDUSTRIAL APPLICATION OF ENHANCED RFS09 SULFUR TRANSFER AGENT IN FCC UNIT

介绍增强型RFS09硫转移剂(简称RFS09硫转移剂)在中国石化北京燕山分公司2Mt/a催化裂化装置上的应用情况,应用结果表明:当RFS09硫转移剂质量分数达到系统藏量的3.50%后,烟气中SO_(2)脱除率达46.43%,总SO_(x)脱除率达51.18%,烟气脱硫塔碱液消耗量降低41.84%,烟气脱硫塔底浆液中溶解性固体总量(TDS)降低39.62%,同时外排烟气蓝色烟羽拖尾现象得到改善;硫转移剂应用期间,未对装置工艺操作、产品分布及产品性质带来不利影响。

The application of enhanced RFS09 sulfur transfer agent(hereinafter referred to as RFS09 sulfur transfer agent) in the 2 Mt/a catalytic cracking unit of SINOPEC Beijing Yanshan Branch Company was introduced. The application results showed that when the sulfur transfer agent mass fraction reached 3.50% of the system inventory, the SO_(2) removal rate in the flue gas could reach 46.43%, the total SO_(x) removal rate could reach 51.18%, and alkali liquor consumption of the flue gas desulfurization tower was decreased by 41.84%. The total dissolved solids(TDS) in bottom slurry of the flue gas desulfurization tower was decreased by 39.62%, and blue plume tailing of the discharged flue gas was improved. During application of the sulfur transfer agent, there was no adverse impact on the process operation, product distribution and product properties of the unit.
