Abstract
A gas-separation method for controlling vapor emissions. The method employs a spiral-wound membrane module, adapted to provide one or more feed-side baffles in the feed channel. The method may be used to control vapor emissions from a volatile liquid, and is particularly useful to control fuel vapors emitted during fuel transfer operations.
