ABSTRACT:
In a membrane apparatus for separating a gas mixture, permeate gas is withdrawn from the vessel housing the membranes along passages whose extent along the flow path of the nonpermeate gas is only a fraction of the extent of such flow path. Thus, the gas mixture to be separated may be passed along the insides of a multiplicity of hollow fibres 8 whose walls are of a suitable membrane and cells 18 for the withdrawal of the permeate gas are defined by partitions 16 extending transversely to the fibres 8. Alternatively, an open-pored foamed plastics may be used instead of the partitions 16, or the gas may pass outside the fibres which are arranged transversely to the general direction of gas flow through the vessel, the permeate gas being withdrawn along the inside of each hollow fibre.
