An improved process and system for separation and recovery¹of perfluorocompound gases |
摘要 |
<p>Processes and systems to recover at least one perfluorocompound gas from a gas mixture are provided. In one embodiment the inventive process comprises providing a gas mixture comprising at least one perfluorocompound gas and at least one carrier gas, the gas mixture being at a predetermined pressure; providing at least one size selective membrane having a feed side and a permeate side; contacting the feed side of the at least one membrane with the gas mixture; withdrawing from the feed side of the membrane as a non-permeate stream at a pressure which is substantially equal to the predetermined pressure a concentrated gas mixture comprising essentially the at least one perfluorocompund gas; and withdrawing from the permeate side of the membrane as a permeate stream a depleted gas mixture comprising essentially the at least one carrier gas. <Fig. 2></p> |
