摘要
酸性铁盐溶液氧化脱H2S是目前世界上比较先进的技术,其具有反应速度快、副反应少、硫磺回收率高和回收剂价格便宜等优点,是目前很有发展前途的H2S脱除方法。主要通过对该方法的原理及影响因素进行分析和研究,提出了最佳的工艺条件:酸性吸收液Fe3+浓度>0.5 mol/L,吸收温度60℃,吸收液高度1 m,气嘴直径0.05 mm,使废气H2S脱除率达99%以上,用于吸收镓生产尾气完全可以实现达标排放。工艺简单,消耗组分价格低廉,具有一定的应用价值。
At present, the H2S removal by oxidation of acidic molysite solution is more advanced technology in the world. It has the advantages of quick reaction, less by - reaction, high recovery of sulfur and low price of the absorbent. So, this method has blooming prospect. The principle and effecting factors of this method are analysed and studied. The optimum process conditions are as follows : the concentration of the acidic absorbing solution c ( Fe^3+ ) 〉 0.5 mol/L, absorbing temperature 60 ℃ ,the height of absorbing solution 1 m,the diameter of gas nozzle 0.05 mm. The removal rate of exhaust gas H2S can be over 99%. This process is simple and the absorbent is cheap, thus,it possesses a valuble application.
