Abstract
A spiral-wound, gas-separation membrane module and a gas-separation process. The module and process provide at least partial counter-current flow between the feed and permeate gas streams without requiring a permeate sweep. The counter-current flow pattern can be achieved by appropriate placement of barriers or baffles in the feed channel. Similar modules and processes may also be used for pervaporation.
