湿式烟气脱硫除尘技术在TMP催化裂化装置的应用

摘要

A new smoke desulfurization dedusting unit by adopting sodium magnesium wet type desulfurization technology was built on 0.3 Mt/a TMP catalytic and cracking plant of Hengyuan Petrochemical Company .The industrial running results showed that the new built des-ulfurization dedusting unit had good operational flexibility and economic stability .Minimum con-tent of SO2 in the purified smoke could reach 3 mg/m3 and the removal rate was 99.9%.The av-erage dust content of the purified smoke was 16.3 mg/m3 and preceded the design value .Each control index on the discharged exhaust gas of the TMP catalytic and cracking unit after reforma-tion met the discharge standard requirement , which realized high efficient and continuous run-ning.%恒源石化在0．3 Mt／a的 TMP 催化裂化装置采用钠镁法湿式烟气脱硫技术，新建1套烟气脱硫除尘装置。工业运行结果表明，钠镁法烟气脱硫除尘装置具有良好的操作弹性，运行经济可靠。净化后烟气中的SO2浓度最低能达到3 mg／m3，SO2脱除率达到99．9％，净化烟气平均粉尘含量16．3 mg／m3，优于设计值。实现了高效连续运行，可控外排废气中的各项指标满足排放要求。
