摘要
简述了王庄煤矿煤化工过程中采取的HPF法脱硫工艺,结合实际生产中脱硫系统长期的运行数据,分析了脱硫系统的温度及脱硫液中氨含量等影响脱硫效果的各种因素。通过对关键脱硫工艺指标进行改进和优化,有效提高了设备的脱硫效率,使得脱硫效率能够保持在98%以上,经脱硫后的煤气中H_2S质量浓度可控制在50 mg/m~3。
This paper briefly describes the HPF desulfurization process adopted in the coal chemical process of Wangzhuang coal mine.Combined with the long-term operation data of the desulfurization system in actual production,various factors such as the temperature of the desulfurization system and the content of ammonia in the desulphurizing liquid and other factors affecting the desulfurization effect are analyzed.After the improvement and optimization of the key desulfurization technology,the desulfurization efficiency of the equipment can be improved effectively and the desulfurization efficiency can be kept above 98%.The concentration of H_2S after desulphurization can be controlled at 50 mg/m~3.
