摘要： This gas purifying process removes trace constituents from a mixed gas that includes a rare gas and nitrogen as main components, and at least one from among hydrogen, nitrogen and hydrogen reaction products, and water vapor as the trace constituent. This process sequentially carries out an adsorbing step for removing water vapor and nitrogen and hydrogen reaction products; a hydrogen oxidation step for converting the hydrogen into water vapor by means of a hydrogen oxidation catalytic reaction in the presence of oxygen; and a drying step for removing water vapor generated in the hydrogen oxidation step. When nitrogen oxides are included as a trace constituent, then a denitration step is carried out prior to the adsorbing step, to convert nitrogen oxides into nitrogen and water vapor by means of a catalytic denitration reaction in the presence of a reducing substance.

摘要： Apparatus and process for removing carbon monoxide from a gas stream comprising a major portion of an inert gas and a minor portion of carbon monoxide are provided. The process involves contacting a feed gas stream with at least a primary metal oxide in a reaction zone of a reactor vessel at conditions effective to convert substantially all of the carbon monoxide to carbon dioxide, thus producing a purified gas stream consisting essentially of the inert gas and carbon dioxide and substantially free of carbon monoxide. This process has (inter alia) a particular application as a tertiary purification process for producing a more highly purified source of gaseous nitrogen from a source of nitrogen originally produced from a conventional membrane air separation system, wherein the oxygen concentration in the nitrogen stream my vary around a setpoint value, and then further (or secondarily) purified by converting excess oxygen in the nitrogen to carbon monoxide and carbon dioxide using a fuel gas/combustion process, wherein the carbon monoxide concentration varies due to varying oxygen concentration in the feed stream to the combustion process.

摘要： Hydrogen and carbon monoxide impurities are removed from a dry gas comprising the impurities, wherein the dry gas is at least substantially free of carbon dioxide, by passing the dry gas with sufficient residence time, e.g. at least 1.5 s, through a layer of catalyst comprising a mixture of manganese oxide and copper oxide. The use of expensive noble metal catalysts to remove hydrogen may thereby be avoided. In addition, regeneration of the catalyst using oxygen-containing regeneration gas does not reduce the effectiveness of the catalyst.

摘要： A process and system for removing trace amounts of oxygen as an impurity in inert gases is disclosed. The process and system involve an electrochemical cell containing an oxygen ion transporting, solid state metal oxide electrolyte having a high thermodynamic potential and having only one thermodynamically stable valence state for the metal ion component of the electrolyte. The electrolyte is coated with a perovskite anode and a metallic cathode. Operation is conducted at high voltages, e.g., 1.5 volts and above, at elevated temperatures. Purification of inert gases to an oxygen content of about 1 ppm is readily achievable.
