Natural Gas Processing

 


Gas gathering device, desulphurization and decarbonization device, dehydration device, dehydrocarbon device, acid gas processing device, condensate oil stabilizing device, amine purification device, valve bank area of external transmission station for purified gas, external transmission station for condensate oil, flare and venting system, condensate oil tank farm.
Main acid gas in the natural gas includes CO2 and H2S; for gas transmission via pipeline, H2S<20mg/m3, and for raw material of methanol synthesis, H2S<1mg/m3. The process where H2S and organic sulfide are separated from acid natural gas is called desulfurization; CO2 removal is called decarburization.
The main purpose of desulfurization is to prevent the generation of sulfur dioxide and other air-polluted gases from burning natural gas; the purpose of dehydration is to prevent the formation of crystalline hydrate in the natural gas during the transmission via pipeline under high pressure to block the pipeline; main purpose of dehydrocarbon and condensate oil is, on one hand, to separate two and more carbon atom compounds from natural gas (e.g. LPG, butane (a component of lighter)) for other more useful purposes; on the other hand, prevent the formation of droplet during the low temperature transmission of natural gas to affect transmission efficiency.
