Treatment
Any gas purification process, but most generally applied to the treatment of gas immediately after production, to bring it to acceptable standard for the market in question and/or to extract valuable components for separate sale. This may involve the removal of LPGs and will certainly involve stripping out Condensates, Carbon Dioxide and Hydrogen Sulphide and other sulphur compounds (see also Acid Gas) mercury and excessive water which may be in the raw gas. Other impurities are occasionally encountered. Whether other inert gases such as nitrogen, helium etc are extracted will be a matter for economic evaluation.
