吸收法制取硫化氢气体的工艺设计

兖矿鲁南化肥厂根据合成氨生产装置的工艺特点,采用聚乙二醇二甲醚溶剂通过物理吸收酸性气及加热再生的方法,对其排出的酸性气体进行处理来制取高纯度硫化氢气体。该工艺流程简单,两塔流程中吸收塔和再生塔均为填料塔,选用新型填料QH-1扁环,成功生产出体积分数大于95%的硫化氢产品。

Technological design for production of hydrogen sulfide through absorption

According to the ammonia synthetic process of Yankuang Lunan Chemical Fertilizer Plant,NHD(selexol)solvent was adopted to produce high pure hydrogen sulfide through physical absorbent and calefaction regeneration,and acidity gas discharged from the ammonia synthetic plant was disposed by it.It's a simple process,the absorbent tower and regeneration tower adopted are packing towers,the new packing material is QH-1,a new flot loop filter.Hydrogen sulfide with the volume fraction higher than 95% can be successfully produced.
