摘要： A method and apparatus for producing a carbon monoxide containing product in which cathode and anode sides of an electrically driven oxygen separation device are contacted with carbon dioxide and a reducing agent, respectively. The carbon dioxide is reduced to carbon monoxide through ionization of oxygen and the reducing agent lowers the partial pressure of oxygen at the anode side to partially drive oxygen ion transport within the device through the consumption of the oxygen and to supply heat. The lowering of oxygen partial pressure reduces voltage and therefore, electrical power required to be applied to the device and the heat is supplied to heat the device to an operational temperature and to the reduction of the carbon dioxide occurring at the cathode side. The device can be used as part of an integrated apparatus in which the carbon dioxide is supplied from a waste stream of a process plant.

摘要： A process and system for recovering valuable by-products (e.g., hydrogen) from refinery gas streams. For hydrogen-only recovery, the invention comprises a partial condensation step to upgrade the refinery fuel gas to a minimum of 60% hydrogen, which is further purified in a pressure swing adsorption process. When configured to recover hydrogen, methane-rich gas and raw LPG (methane depleted gas containing C2 hydrocarbons and heavier), the invention comprises two partial condensation steps where the feed is cooled in the first step to allow separation of ethane and heavier hydrocarbons, and the resulting vapor is cooled to a lower temperature in a second step for hydrogen recovery.
