Title:
MASS TRANSFER METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO1995035153
Kind Code:
A3
Abstract:
The invention relates to a method for transferring mass between a flow of a first fluid and a flow of a second fluid, one of the fluids being a gas phase and the other being a liquid phase, the method comprising contacting the first fluid with the outer surface of a plurality of hollow tubular members, at least part, but preferably substantially all, of the walls of the hollow tubular members comprising porous membranes with gas-containing pores and contacting the second fluid with the inner surface of said hollow tubular members, the maximum pore size of said membranes being such as to prevent direct mixing of the two fluids, the wall morphology of the membranes being so adapted that the mass transfer coefficient of the membranes with respect to the mass transfer in question is at least one tenth of the mass transfer coefficient of the gas phase, the hollow tubular members being arranged parallel to each other or at angles to each other, the plurality of hollow tubular members defining interstices therebetween through which interstices the first fluid is moved in a transverse direction relative to the longitudinal direction of the hollow tubular members.
