본 발명의 이산화탄소 포집 장치 및 이산화탄소 포집 공정의 암모니아 휘발 억제 방법을 사용함으로써, 암모니아의 휘발을 효과적으로 억제할 수 있으며, 암모니아 회수를 위한 세정수의 사용을 저감시킴으로써 농축탑에서 소모되는 에너지를 저감시켜 공정의 운전비용을 절감시킬 수 있다.
The invention absorbs carbon dioxide in the ammonia water from the carbon dioxide-containing off-gas discharging exhaust gas, comprising a porous medium layer inside the absorption tower; And a carbon dioxide-containing aqueous ammonia absorbed carbon dioxide from the absorption column is supplied to the carbon dioxide from the supplied containing carbon dioxide ammonia by heat discharged to the gas phase, and play an ammonia water, comprising a regeneration column containing a porous medium layer therein in the porous medium layer, while the exhaust gas or carbon dioxide in the regeneration tower of the absorber is passed through the condensation of the ammonia contained in the exhaust gas or carbon dioxide to provide a carbon dioxide collecting device is separated. The present invention also provides a suppressing ammonia volatilization of carbon dioxide absorption process comprising a carbon dioxide removal step, the exhaust gas in an ammonia stripping step, ammonia and carbon dioxide in the regeneration step the ammonia stripping step method.
By using the inhibition of ammonia volatilization method of the carbon dioxide absorption unit and the carbon dioxide absorption process of the invention, it is possible to suppress the volatilization of ammonia, effectively, by reducing the energy consumption in the concentration tower by reducing the use of the number of washing for the ammonia recovery process the operating costs can be reduced.
