Abstract

See full text

Provided is an apparatus for recovering amines from amine-containing waste water generated in power stations, etc., and regenerating a cation exchange resin. The apparatus includes: a cation exchange resin layer capturing amines from amine-containing waste water and eluting the amines therefrom; a degassing tower degassing the eluted amines; a vacuum pump connected to the degassing tower; and a condensation and cooling tower condensing the degassed amines at a temperature of −33° C. or lower, wherein the amines captured in the cation exchange resin layer are eluted by injecting a strong acidic solution, while the resin is regenerated, and the amines eluted by the strong acidic solution is subjected to vacuum degassing and then recovered. Provided also is a method for recovering amines and regenerating a cation exchange resin using the apparatus. The apparatus and method for recovering amines and regenerating a cation exchange resin improve the quality of effluent water from power stations, etc., and increase the cost-efficiency through the recycle of amines.
