A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.
