▎ 摘　　要

NOVELTY - An apparatus comprises a graphene oxide membrane (1) for drying the air flow (4), and comprising a layer of graphene oxide supported on a porous support, and an air separation unit for separating the gases from the dried air stream (6). USE - Apparatus is used for separating gases such as hydrocarbon, nitrogen oxide and sulfur oxide from air stream comprising water vapor (claimed). ADVANTAGE - The apparatus can efficiently separate gases from air stream. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for process for separating gases from air stream comprising water vapor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the apparatus. Graphene oxide membrane (1) Flow duct of air flow (2) Air flow (4) Dried air stream (6) Water stream (7)
