A filtration apparatus that separates a liquid feedstock mixed with a gas
into filtrate and retentate, the apparatus including at least one
filtration device comprised of at least one monolith segment of porous
material that defines a plurality of passageways extending longitudinally
from a feed face of the structure to a retentate end face. The filtration
device contains at least one filtrate conduit within it for carrying
filtrate toward a filtrate collection zone, the filtrate conduit
providing a path of lower flow resistance than that of alternative flow
paths through the porous material of the device. The filtration device
can also be utilized as a membrane support for a device for
microfiltration, ultrafiltration, nanofiltration, reverse osmosis, or
pervaporation. Also disclosed is a method for using such a filtration
apparatus.
