초록 ▼

A hollow fiber separation module is provided having a single, elongated pressurizable shell and containing multiple separation stages by multiple sections of hollow fiber bundles contained within the shell, with the ends of each bundle section potted within a single tubesheet at each end of the elongated shell. The fibers within each section are aligned so that the permeate within the fiber bores passes along paths traveling generally from one tubesheet to the other and one or more impermeable barriers are provided within the shell to isolate each section and control the passage of feed gas along the shell side of each fiber bundle section in a flow path countercurrent to the passage of permeate in the bores of the fibers.

대표청구항 ▼

A hollow fiber shell side feed separation module comprising: (a) a pressurizable shell; (b) an elongated bundled of hollow fibers within said shell, said fibers formed from semipermeable membrane material capable of separating components from a fluid feed mixture, said fibers aligned generally along paths running from one end of said bundle to the other end; (c) first and second tubesheets embedding first and second ends, respectively, of said bundle and sealing the bores of said fibers from the fiber exteriors between said tubesheets; (d) at least one impermeable wall member extending longitudinally through said bundle and partitioning said bundle between said tubesheets into at least first and second sections wherein said impermeable wall member contains a passageway in close proximity to the second tubesheet, each fiber between the tubesheets lying completely within one or the other of said sections; (e) means for introducing a fluid feed mixture into said first section on the shell side of the fibers adjacent to said first tubesheet; (f) means for passing said feed mixture along the exterior of the hollow fibers in said first section and then through said passageway and along the exterior of the hollow fibers in said second section, wherein permeate passes to the interior of said hollow fibers in said first section and said second section, such that said feed mixture is in countercurrent flow with permeate; (g) means for removing retentate from said second section adjacent said first tubesheet; (h) means for removing retentate from said shell; (i) sealing means cooperating with said tubesheets for sealing the bores of the fibers of each section from the bores of the fibers in any other section and defining discrete collection zones for permeate from the bores of the fibers of each section; (j) means for withdrawing a first permeate from the collection zone of said first section adjacent said first tubesheet; and (k) means for withdrawing a second permeate from the collection zone of said second section adjacent said second tubesheet.
