<p>PROCESS FOR SEPARATING ONE GAS FROM A GAS MIXTURE A process for separating one gas from a feed gas mixture containing the one gas wherein the mixture is brought into contact with one side of a membrane more permeable to the one gas than the other gases of the mixture and the permeated gas is recovered from the other side of the membrane. In order to maintain the process at a substantially constant rate of recovery at varying feed gas flow rates and/or pressures, the rate of recovery is sensed and the gas mixture is heated or cooled to vary its temperature in proportion to variations in feed gas flow rates and/or pressure such that the rate of recovery remains substantially constant. The rate of recovery may be measured in terms of purity of the permeated gas in the separated gas stream, the amount of gas recovered in a given time period or the percentage of the one gas separated from the feed gas mixture.</p> |
