Abstract

An adsorptive separation device is disclosed having at least one spiral wound adsorption membrane situated around the periphery of a core mandrel wherein the flow is radial from a feed plenum situated between the core mandrel and the membrane, through the membrane to a permeate plenum located between the membrane and a housing for both the core mandrel and the spiral wound membrane. An array of such separation devices is also disclosed showing connections in parallel, in series, in both parallel and in series and in tandem.
