Abstract
A system and process are described for increasing the concentration of a combustible component of a gaseous mixture containing such component (e.g. methane) and an additional gaseous component (e.g. carbon dioxide), wherein the gaseous mixture is contacted with a permselective membrane which is permeable to both such components and has selectivity for the additional component. A pressure difference is maintained across the membrane. At least a portion of the energy employed to maintain the pressure difference is provided by combustion of at least a portion of the combustible component which has permeated through the membrane.
