Abstract
The present invention relates to a crossflow membrane module configured to separate a feed fluid into a permeate fluid and a residue fluid across one or more membrane sheet(s). The crossflow module comprises a second end offset from a first end along the first direction where an inlet is provided at the first end and an outlet is provided at the second end. The one or more membrane sheet(s) each have a first portion and a second portion. A conduit is adjacent to the first side of each membrane sheet and is configured to receive and output the permeate fluid separated from the feed fluid. The second portion of the membrane sheet has a greater permeance for a major component than the first portion such that the second part of the permeate fluid, which is generated by separation across the second portion of the membrane sheet, has a higher concentration of the major component than the first part of the permeate fluid, which is generated by separation across the first portion. The second portion is spaced apart from the first side of the membrane sheet along the second direction thereby causing the second part of the permeate gas to flow towards the first side of the membrane sheet such that the second part of the permeate gas mixes with the first part of the permeate gas thereby reducing the concentration of the minor component in the first part of the permeate gas.
