Abstract
A heat and mass exchange, pressure and/or thermal swing adsorption process using an adsorbent bed which consists of at least one unit having substantially parallel passages through it. Each unit has at least 20 passages per cm.sup.2 of its cross-sectional area, the number and cross-sectional area of the passages being such that each unit has a geometric void of not more than 0.45. The bed may be random packed or a close packed assembly or stack of units.
Claims10
A heat and mass exchange, pressure and/or thermal swing adsorption process for separating a gaseous mixture containing a more readily adsorbed component, or components, and a less readily adsorbed component, or components, into a first stream that is enriched, relative to said mixture, in respect of said less readily adsorbed component, or components, and a second stream that is enriched, relative to said mixture, in respect of said more readily adsorbed component, or components, wherein the adsorbent bed consists of one or more units formed from an adsorbent material effective to adsorb said more readily adsorbed component, or components, preferentially relative to said less readily adsorbed component, or components, each of said units having a plurality of substantially parallel passages extending therethrough, each unit having at least 20 passages per cm.sup.2 of the cross-sectional area of said unit, the number and cross-sectional area of said passages in each unit being such that each unit has a geometric voidage of not more than 0.45.
