| Abstract: | This article analyses the reasons for higher hydrogen sulfide content of coal gas in AS production engineering.By analysis,the following methods are adopted to solve the problem： using NaOH solution rewash the coal gas in the lower part of ammonia washing tower,improving the quantity proportion between ammonia and hydrogen sulfide of washing water into the hydrogen sulfide washing tower,controling the absorption temperature,improving the flow of washing water into the hydrogen sulfide washing tower. |
