Gas separation

In this work, the effects of major spinning parameters, such as: polymer concentration, air gap distance, bore fluid composition, and take-up velocity on the structure and the permeation properties of polyethersulfone-polyimide gas separation hollow fibers are discussed in detail. It is shown that a

To control membrane plasticization in natural gas streams containing higher hydrocarbon compounds, we propose to coat a hydrocarbon-based polymer gas separation membrane with a fluoropolymer layer to reduce the hydrocarbon penetrant partial pressure to which the hydrocarbon membrane is exposed. A th
