Natural gas has gained prominence in the energy scene as a rising fossil fuel following the development of new drilling technology that set up a boom in shale gas production. As crude oil, natural gas contains wide-ranging impurities in addition to the main component, methane. Natural Gas Processing removes the contaminants in the raw gas and recovers some valuable byproducts, such as natural gas liquids. A number of separation and recovery processes used in a petroleum refinery can also be used for natural gas processing.
