It is therefore commonly produced by purifying natural gas. Pure methane may also be obtained from the cracking of petroleum fractions.Applications Methane is used as a heating fuel for domestic-purposes and above all for industrial heating:in the steel industry, with open hearth furnaces, in the presence of fuel oil, and in a reheating furnaces for semi-products prior to rolling or, forging, oxycutting of metal, for heat treatment of nonferrous metals, and supply to infrared heating elements used for surface treatmentIn thermal power plantsIn glass making, annealing kilns for pharmaceutical ampoules, ceramic kilnsIn the textile industryIn the chemical industry, petrochemical furnaces, heating of tanks containing resins for paints, vulcanization of plasticsIn food and farm industries, coffee roasting ovens, malt drying in breweries, dehydration of plant fodder, powdered milk productionIn cement plantsIn paper millsNatural gas is also used as an internal combustion fluid for vehicles.Methane was employed in the gas batteries used by the Apollo space missions.High purity methane is used as a fuel gas in flame photometers. When mixed with argon or xenon, methane is used as a gas filling for proportional counters and other types of radiation detectors.In the chemical field, methane serves as a raw material for the production of methanol, synthetic, ammonia, acetylene, carbon black, carbon disulphide, hydrocyanic acid, methyl chloride, methylene chloride, carbon tetrachloride and chloroform.In the steel industry, natural gas is used for direct reduction of powdered minerals, and to produce hard metal.Methane finds extensive use in various mixtures for quality control laboratories in the petrochemical and fuel gas industries.Methane is used in gas cooled nuclear reactors. The methane is used to dope the carbon dioxide coolant in order to prevent erosion of the carbon control rods in the nuclear core. Methane is used for testing of gas burners.Methane is also used in synthetic town gas mixtures.Methane mixtures are commonly used for calibrations in the automotive industry and in the environmental field.
