Abstract: An example electrolysis system for the electrochemical production of ethylene oxide includes an electrolysis cell having an anode in an anode space and a cathode in a cathode space and a gas separation element. The cathode space has a first inlet for carbon monoxide and/or carbon dioxide. The anode space is integrated into an anolyte circuit and the cathode space is integrated into a catholyte circuit. The catholyte circuit has a first product outlet for a reduction product joined to a first connecting conduit connected to the anolyte circuit. The anode space is configured for bringing a reduction product introduced via the first connecting conduit into contact with an oxidation product.
