A process for separating large percentages of aggressive gases such as carbon dioxide from low temperature gas mixtures wherein the gas mixture is passed through a plurality of treatment zones in series. In each treatment zone the gas mixture is first compressed to a pressure such that the partial pressure of the carbon dioxide is not greater than the critical carbon dioxide partial pressure and the compressed gas mixture is then brought into contact with a membrane more permeable to carbon dioxide than other gases of the mixture such that carbon dioxide...
A process for separating an aggressive gas from a mixture of said aggressive gas and at least one other gas, comprising (a) passing the gas mixture through a plurality of treatment zones connected in series, (b) in each zone first compressing the gas mixture, (c) then in each zone bringing the compressed gas mixture into contact with a feed side of a membrane having a critical partial pressure for the aggressive gas and being more permeable to the aggressive gas than said other gas such that the aggressive gas permeates the membrane to the other side the...
