ETHANOLAMINE RECOVERY METHOD WITH PHYSICOCHEMICAL PROCESS

摘要

A method for withdrawing ethanolamine using a physicochemical process is disclosed. The method withdraws expensive ethanolamine contained in wastewater as follows. The ethanolamine-containing wastewater discharged from nuclear power plants and thermal power plants undergoes an ethanolamine capturing and condensing process using a cation exchange resin. The ethanolamine captured and condensed wastewater undergoes a first evaporation process heating it to 60- 1000C. The wastewater having undergone the first evaporation process undergoes a second evaporation process heating it to 100~200°C.
