Gas Composition
Gas Composition is a term that refers to the measurement and determination of the types and proportions of various gases contained in a gas mixture. Gas composition is very important in various industries, including oil and gas, chemical, environmental, and many others, because it can affect the production process, product quality, and safety and environmental aspects.
DnD Java Laboratory provides quality and component analysis of natural gas. Natural gas testing includes analysis of conventional and shale gas, LNG, and condensate and other hydrocarbon components. The gases analyzed include hydrocarbons (C1 to C6+) such as methane, ethane, propane, iso-butane, n-butane, iso-pentane, n-pentane, and hexane, plus heavier molecules.
Natural gas laboratory tests for trace impurity detection levels. Trace impurities in natural gas include hydrogen, nitrogen, carbon monoxide, carbon dioxide, oxygen, mercury, sulfur, water, and other components.
