摘要：
Hollow-fiber membranes were prepared to remove volatile organic vapors (VOCs) from a nitrogen or air stream. Conditions were found to spin hollow fibers of high performance for the removal of VOCs. The effect of temperature on the permeation of nitrogen gas and acetone vapor was studied. It was found that nitrogen permeation was governed by diffusion while vapor permeation was governed by sorption. There were two distinct mechanisms for vapor permeation, depending on temperature. Performance data for hollow fibers with and without a silicone rubber coating at the internal surface were compared. The effect of the presence of water vapor in the feed was also studied.
