Abstract: A membrane suitable for separating a gas from a gas mixture comprising a non cross-linked PVAm having a molecular weight of at least Mw 100,000 carried on a support wherein after casting onto the support, said PVAm has been heated to a temperature in the range 50 to 150° C., e.g. 80 to 120° C.

Abstract: A membrane contactor system for separating CO2 from a mixed gaseous feed stream comprising CO2, said contactor system comprising: (i) a composite membrane, said membrane having a permeate side and a retentate side; (ii) said retentate side being exposed to a mixed gaseous feed stream comprising carbon dioxide; (iii) said permeate side being exposed to a carbon dioxide capture organic solvent; (iv) said composite membrane comprising a porous layer and a non-porous selective polymer layer, said non-porous selective polymer layer selectively allowing transport of CO2 across the composite membrane from said mixed gaseous feed stream so that it dissolves in said capture solvent whilst limiting the transport of said capture solvent across the composite membrane.
