摘要： A process for separating a feed gas comprising a polar gas and a non-polar gas into a permeate gas and a retentate gas, one of which is enriched in the polar gas and the other of which is depleted in the polar gas, the process comprising passing the feed gas through a gas separation module comprising: (i) a feed carrier comprising a membrane envelope and a feed spacer located within the membrane envelope; and (ii) a permeate carrier comprising: (a) a macroporous sheet; and (b) a protective sheet; and wherein: i) the feed gas is fed along the feed spacer of the feed carrier and a part of the feed gas passes through the membrane envelope and into the permeate carrier to give the permeate gas and a part of the feed gas is rejected by the membrane to give the retentate gas; ii) the protective sheet shields at least a part of the membrane envelope from contact with the macroporous sheet; and iii) the protective sheet comprises a non-woven material.

摘要： A gas-separation module comprising: a) a permeate collection tube comprising a hollow cylinder provided with perforations oriented along the longitudinal axis of the cylinder; and b) at least seven membrane envelopes wound spirally around the permeate collection tube; wherein: (i) the membrane envelopes each comprise a feed spacer and gas- separation membrane(s), wherein the feed spacer is disposed between the gas-separation membrane(s) to define a feed channel and wherein the feed spacer comprises a polymer having a Tg above 0°C; (ii) the module comprises a permeate channel between each of the membrane envelopes in gas-communication with the perforations; and (iii) the permeate collection tube and the membrane envelopes are disposed such that when the module is in use, feed gas entering the feed channel can pass through the perforations only after passing through the gas- separation membranes from the feed channel to the permeate channel. Also claimed are gas separation units and a process for separating gases.
