The gas permeation performance of Polyvinyl Chloride (PVC) membrane was investigated for N2, O2, CH4 and CO2 gases. At 10 bar feed pressure and 25 ºC the CO2/CH4 and CO2/N2 ideal selectivity of 40.36 and 20.18 was observed ...

Researchers have focused on improving the performance of polymeric membranes through various methods, such as adding inorganic nanoparticles into the matrix of the membranes. In the present study, the separation of oxygen, ...

. The thermal properties of PVC membranes were also improved by adding silica particles. The performances of prepared membranes in gas separation were measured at pressure of 10 barg and temperature of 25 ◦C. The obtained results showed that the permeability...

In this study, PEBAX/PES composite membranes were prepared by coating the porous PES support layer by PEBAX-1657. SEM images were used to determine the structure of the membranes. CH4 and CO2 gases were used to measure the ...

The structural properties and gas permeation of a group of copolyimide membranes were investigated. The copolyimides used in this study were prepared using 3,30,4,40-benzophenonetetracarboxylic dianhydride (BTDA) and ...
