  • Partition fluid separation
    Patent number: 9132388
    Abstract: A pervaporation element includes a ceramic monolith having an array of parallel channels separated by porous channel walls extending along an axial length of the monolith, and a functional membrane coating a first plurality of the porous channel walls along the axial length of the monolith. The functional membrane functions to separate a fluid into a retentate portion and a permeate portion. The porous channel walls coated by the functional membrane define a plurality of discrete through segments, where each of the discrete through segments are separated from one another by a plurality of uncoated porous channel walls. Fluid entering the discrete through segments is separated into a retentate portion that exits in substantial portion 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.
