| Abstract: | The membrane technology for producing nitrogen-enriched air is widely used in petrochemical industry.The stream is available for use in enhanced oil recovery of various oil fields,which have viscous oil reservoir and extremely low permeability oil reservoir and so on,for use in drilling,well completion,nitrogen protection & replacement,solvent recovery with nitrogen stripping.Generally speaking,using nitrogen-enriched air produced by membrane technology can gain comprehensive benefits both socially and economically. |
