莱芜市泰山焦化有限公司脱硫塔后硫化氢含量一直偏高。通过采取导热油替代蒸汽、提高进蒸氨塔氨水温度、降低进蒸氨塔前氨水中焦油含量等措施优化蒸氨系统，采取泡沫调节、提高脱硫液质量、调整催化剂添加量等措施优化脱硫系统，实现了双级脱硫，硫化氢含量由2013年的1200 mg/m3降低到2014年的180 mg/m3，达到国家排放标准。

Hydrogen sulfide has been in a high level after desulfurization tower in Taishan coking company of Laiwu City. The thermal oil is used instead of steam, the temperature of ammonia water that entering the ammonia still is improved, the tar content in ammonia water before ammonia still is reduced, so that ammonia distillation system is optimized. Through some desulfurization measures included foam adjustment, improving quality of desulfurizing solution, adjusting the catalyst amount and so on, two-stage desulfurization is realized. Hydrogen sulfide content is reduced from 1 200 mg/m3 in 2013 to 180 mg/m3 in 2014, which has meet the national discharged standard.
