Dicyclohexylamine Tail Gas Refining Method
The refined hydrogen concentration can reach 98.0-99.8%, reducing material consumption and energy consumption, and achieving the purpose of energy saving and emission reduction. It can be used as circulating gas for hydrogenation of aniline to achieve zero gas emission.
The invention relates to a tail gas refining method, especially a method for hydrogenation of aniline to produce dicyclohexylamine tail gas deamination and hydrogen refining, which belongs to the technical field of chemical industry.
The dicyclohexyl amine device of exhaust emissions by roche hydrogen compressor, degreaser, into ammonia absorption tower, the tower, a large amount of ammonia are transformed into ammonia water absorption by the bottom output, output for aqueous hydrogen gas composition, the tower will aqueous hydrogen gas by water segregator, fiber filters, water adsorption tower further to remove water vapor, hydrogen refining.
