Abstract:
1. A pervaporation element comprising: a ceramic monolith having an array of parallel channels separated by porous channel walls extending along an axial length of the monolith, wherein a plurality of the porous channel walls are uncoated porous channel walls; a functional membrane coating a first plurality of the porous channel walls along the axial length of the monolith, the functional membrane functioning to separate a fluid into a retentate portion and a permeate portion, wherein the first plurality of porous channel walls coated by the functional membrane define a plurality of discrete through segments and wherein the uncoated porous channel walls separate each of the discrete through segments such that fluid entering the discrete through segments is separated into a retentate portion that exits through the discrete through segments and a permeate portion that exits the ceramic monolith radially outward through the uncoated porous channel walls and through a skin of the monolith; and a segmented end cap secured to an axial end of the ceramic monolith, the segmented end cap having a plurality of openings positioned to expose the plurality of discrete through segments and cover the uncoated porous channel walls such that the segmented end cap directs the fluid to flow into the plurality of discrete through segments.
