二硫化碳尾气的分离和综合利用

The Separation and Complex Utilization of the Carbon Disulfide in Tail Gas

利用活性碳吸附二硫化碳生产尾气中的CS2等物质,得到较纯净的H2S。利用低压蒸汽对活性碳进行解吸回收CS2。H2S和氨水反应生成(NH4)2S产品,取得良好的经济效益和环保效益。

The activated carbon was used to adsorb the carbon disulfide etc. in tail gas of carbon disulfide production to get the pure hydrogen sulfide. Making use of low-pressure steam, the activated carbon was solved and adsorbed to recycle the carbon disulfide. The hydrogen sulfide reacted with the ammonia water formation ammonium sulfide. Good economic results with environmental protection performance were both obtained.
