Tubular solid-state membrane modules for separating oxygen from an oxygen-containing gaseous mixture which provide improved pneumatic and structural integrity and ease of manifolding. The modules are formed from a plurality of tubular membrane units, each membrane unit which comprises a channel-free porous support having connected through porosity which is in contact with a contiguous dense mixed conducting oxide layer having no connected through porosity. The dense mixed conducting oxide layer is placed in flow communication with the oxygen-containing gaseous mixture to be separated and the channel-free porous support of each membrane unit is placed in flow communication with one or more manifolds or conduits for discharging oxygen which has been separated from the oxygen-containing gaseous mixture by permeation through the dense mixed conducting oxide layer of each membrane unit and passage into the manifolds or conduits via the channel-free porous support of each membrane unit.
A module for separating oxygen from an oxygen-containing gaseous mixture comprising a plurality of tubular solid-state membrane units, each tubular solid-state membrane unit which comprises a channel-free tubular porous support having connected through porosity which is in contact with a contiguous tubular dense mixed conducting oxide layer having no connected through porosity and at least one channel which is contiguous to the tubular channel-free porous support on a side opposite the tubular dense mixed conducting oxide layer, wherein the tubular dense mixed conducting oxide layer is in flow communication with the oxygen-containing gaseous mixture to be separated and wherein the tubular channel-free porous support of each membrane unit is in flow communication with a removal means for discharging oxygen which has been separated from the oxygen-containing gaseous mixture by permeation through the tubular dense mixed conducting oxide layer of each membrane unit and passage into the removal means via the tubular channel-free porous support of each membrane unit.
