Membranes made of PEBA block copolymer have very interesting separation properties for gas pairs where CO2 appears. Using these membranes, one can remove CO2 from the various gas streams. Owing to this property, the use of these membranes for processing of natural gas or gas streams obtained from biomass conversions appears to be of great interest. Flat membranes and composite capillary membranes both made of copolymer PEBA have been prepared and their separation properties have been investigated. Primary tests have been conducted for CO2 and N2 using commercial polymer Pebax® 1074.
