A macroporous polymeric adsorbent is used to remove oil mist and oil vapors from compressed air produced by an oil-lubricated air compressor prior to feeding the compressed air to an air separation membrane system. The macroporous polymeric adsorbent, previously known only for its ability to extract low molecular weight volatile organic compounds from liquids and gases, retains its ability to extract the oil for extended periods of time and outperforms the commonly used activated carbon of the prior art.

[ We claim:] [1.] A process for separating a gas mixture into components by permeation through a membrane, the process comprising:a) compressing the gas mixture in oil-lubricated compression means to form an oil-mist-containing compressed gas stream;b) directing the compressed gas stream through a heater;c) passing the compressed gas stream, after it leaves the heater, through a macroporous polymeric adsorbent;d) transferring heat from the compressed gas stream exiting the macroporous polymeric adsorbent to the compressed gas stream before said compressed gas stream enters the heater; and(e) passing the substantially oil-free compressed gas stream, exiting the macroporous polymeric adsorbent, through a gas separation membrane system.
