摘要
介绍了AS煤气脱硫工艺流程、工艺特点及关键点控制,指出还存在的问题及改进的途径。该工艺将煤气洗氨与脱硫结合在一起,以氨汽为热源使脱硫液再生,增加了脱硫贫液中游离氨的含量,具有较高的脱硫效率。
An introduction is given to the process flow,process features and key point control of AS gas desulphurization and the existing problems and ways for improvement are pointed out.In the process,the ammonia scrubbing of gas is combined with desulphurization and ammonia is used as heat source to make desulphurized solution regenerate and increase the free ammonia content in desulphuring lean solution.AS gas desulphurization process has higher desulphurization efficiency.
