摘要：
A method for removing contaminants from natural gas streams. The natural gas stream is fed to a dryer, then a membrane module and a multibed, multilayer vacuum swing adsorption process for removal of oxygen, nitrogen and carbon dioxide from the natural gas stream. Alternatively when carbon dioxide is in relatively low concentration in the natural gas stream, the membrane module step is not employed.
