Examples of uses of this molecule in Industry and Healthcare
The main current chemical usage of methane is the production of synthesis gas (Syngas), H2 and CO via Steam Methane Reforming (SMR) of natural gas. Synthesis gas is then converted into methanol, oxo-alcohols, ammonia and hydrocarbons. Methylhalogenides (e.g. methylchloride), HCN and acetylene are also produced from methane.Chemicals
Methane is the main component of natural gas, a primary energy resource widely used in the energy sector for the production of heat and/or electricity. Natural gas as compressed natural gas (CNG) or liquefied natural gas (LNG) are increasingly used as fuels for vehicles to reduce transport emissions and improve air quality.New energies
Methane is a component of a gaseous mixture used for pulmonary function diagnosis test.Hospital care
Methane is used in calibration gas mixtures for petrochemical industry, environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers. In mixture with argon, methane is used in Geiger counter and in X-ray fluorescence detector as quentching gas. In mixture with other hydrocarbons, methane is used as reference point in calorimetric measurements of hydrocarbons or coal.Laboratories & Research Centers
Methane can be used in blast furnace and Direct Reduced Iron (DRI) plants, as well as cooling agent for tuyeres.Metal
Methane provides carbon source to silicon film to adjust the light absorption bandgap in silicon thin film photovoltaics.Electronic components

Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.

Methane was discovered between 1776 and 1778 by Alessandro Volta. It can be found in natural gas reservoirs below ground and oceans. When in the atmosphere, it contributes to the GreenHouse effect, i.e it retains heat on earth.
