Abstract

See full text

The present invention provides a process for recovering a basic amine compound which comprises the steps of (a) supplying a CO.sub.2 -containing gas to a carbon dioxide absorption unit in which an absorbing solution, which contains a basic amine compound, absorbs carbon dioxide; (b) bringing the gas, from which carbon dioxide has been removed, into vapor-liquid contact with a washing water at a temperature from 20 to 60.degree. C. in an amine recovering unit of a carbon dioxide removal tower, recovering part of the basic amine compound accompanying the gas into the water phase and discharging the gas as an exhaust gas of the carbon dioxide removal tower; and (c) collecting the basic amine compound which remains in the exhaust gas of the carbon dioxide removal tower by passing the exhaust gas pass through a demister at a temperature from 20 to 60.degree. C. The basic amine compound can be recovered efficiently from the gas of the carbon dioxide removal tower by using the above process.
