MEMBRANE DEVICE AND PROCESS FOR MASS EXCHANGE, SEPARATION, AND FILTRATION

摘要

A membrane device and processes for fabrication and for using are disclosed. The membrane device may include a number of porous metal membranes that provide a high membrane surface area per unit volume. The membrane device provides various operation modes that enhance throughput and selectivity for mass exchange, mass transfer, separation, and/or filtration applications between feed flow streams and permeate flow streams.

主权项

1. A membrane device, comprising:
one or more membrane cassettes disposed in a stack of membrane cassettes, each membrane cassette includes porous metal membranes disposed on respective sides of a support frame, the membrane cassettes provide a plurality of feed flow slots and a plurality of permeate (or sweep) flow slots on respective sides of the membrane device with flow channels that transport selected fluids across the surfaces of the porous membranes in the membrane cassettes during operation that provide separation or filtration of particulates or molecules of a selected size from the fluids introduced into the membrane device.
