Many polymers like PS, PES, PE, are used for separation of carbon dioxide from methane and there is some inorganic particle such as nano-silica, SAPO-34, TIO2 with hydrophilic properties that good affinity to separate water vapor from organic compound.
I am looking for the best polymer and inorganic particle to fabricate the best mixed matrix membrane with a good properties for CO2 and water vapor separation from natural gas simultaneously.
Highly permeable glassy polymeric membranes based on poly (1-trimethylsilyl-1-propyne) (PTMSP) and a polymer of intrinsic porosity (PIM-1) were introduced for water sorption, water permeability and the separation of CO2 under humid mixed gas conditions. The water vapor permeability through both membranes are a function of temperature, and found to be at a minimum at 80 °C for PTMSP and 70 °C for PIM-1. This temperature dependence is a function of reducing water solubility in both membranes with increasing temperature countered by increasing water diffusivity.
but Introducing water vapor further reduced the CO2 permeability.
