RISSeparation of H2S from CH4 by polymeric membranes at different H2S concentrations
سال: 2017
خلاصه:
In this work, permeation of mixed gases H2S/CH4 through commercial polyphenylene oxide (PPO) hollow fiber and poly (ester urethane) urea (PEUU) flat membranes was studied at pressures of 345–689 kPa, at ambient temperature ...
The Effect of Ethane on the Performance of Commercial Polyphenylene Oxide and Cardo-type Polyimide Hollow Fiber Membranes in CO2/CH4 Separation Applications
سال: 2009
خلاصه:
Impurities such as hydrogen sulfide, water vapor and heavy hydrocarbons in natural gas have considerable effects on the membrane performance. Small amounts of condensable and polymer soluble components in the feed gas cause ...
Removal of hydrogen sulfide from methane using commercial polyphenylene oxide and Cardo-type polyimide hollow fiber membranes
سال: 2009
خلاصه:
The performances of commercially available poly (2,6-dimethyl-1,4-phenylene oxide)(PPO) and Cardo-type polyimide (PI) hollow fiber membranes were investigated in removing hydrogen sulfide from methane in a series of ...
