Method of recycling process gas in electrochemical processes

摘要

A method of recycling process gas into an electrochemical process comprising at least one gas diffusion electrode, the method comprising: feeding feed gas into the electrochemical process via a gas jet pump under a pressure which exceeds a process pressure, expanding the feed gas to process pressure in a gas jet pump, and generating a suction pressure which is less than the process pressure, and aspirating feed gas-containing tail gas by means of the suction pressure generated in a gas jet pump and recycling the tail gas into the electrochemical process.
