Abstract
A process for removing carbon dioxide (CO) by means of an absorption medium from a cycle gas system, wherein the COoccurs within a process in which, in the gas phase, ethylene is oxidized by oxygen (O) to ethylene oxide (EO) in the presence of a catalyst, in which, as by product, COis generated, by using as absorption medium an aqueous solution of one or more amines, wherein, for further purification of the cycle gas stream obtained downstream of the COabsorption step, this cycle gas stream is brought into intimate contact with water to which no mineral acid and no higher glycol was added.
