Production of membrane for co₂/n₂separation effect of diluents extraction time on pp-dpe membrane

The main factors that contribute for the raising of global warming are CO₂ gas. Production of membrane is actually one of the methods for the separation of CO₂ gas. Membrane technology is continuity and simplicity process compared to the others conventional separation technology. The membranes were...
