ABSTRACT:
A method and apparatus for removal of acidic gases from a gas stream by contacting the gas stream with an amine vapor in a reaction zone. The partial pressure of amine vapor in the reaction zone is at least 5 percent of the total pressure therein, resulting in removal of at least 99 percent of the acidic gases. When operating at ambient temperature and substantially atmospheric pressure, preferred amines are methylamine and dimethylamine.
