| Abstract: | In case the ammonia distillation capacity is insufficient,the surplus ammonia could be utilized for ammonia cleaning,thus,the ammonia content in the coke oven gas after the washing column could be decreased.After proper hooking up and revamping of the existing piping,tanks and heat exchangers of the washing unit,the surplus ammonia water could be used to absorb ammonia from the coke oven gas,as a result,the ammonia in the coke oven gas could be decreased to a great extent. |
