Natural gas is a naturally occurring hydrocarbon gas. It mainly consists of methane and certain percentage of carbon dioxide (CO2), hydrogen sulfide (H2S), nitrogen, and varying amounts of higher alkanes. Natural gas is normally associated with other fossil fuels in coal beds. Elimination of CO2 from natural gas has recently become a worldwide matter. In addition, natural gas needs to meet the sales gas and pipe specifications and effective liquefaction of natural gas processes to produce liquefied natural gas (LNG). It is essential to reduce the CO2 emissions to atmosphere to combat global warming. The most common method to remove CO2 is amine absorption. Pressure swing adsorption, distillation, and membranes are emerging techniques for CO2 capture. This chapter presents the diverse processes existing and appropriate for the capture of CO2 from natural gas to meet natural gas sales and pipe product specifications.
