A gas-separation module allows a sweep gas to be introduced at selectively variable locations, and in selectively varying amounts, along the length of the module. The sweep gas enters the module through a perforated conduit. A slotted sleeve, disposed within the conduit, selectively blocks and unblocks perforations in the conduit. Rotation of the sleeve causes slots to come into, or out of, registration with the perforations. The sleeve permits varying amounts of sweep gas to be introduced at different locations along the length of the module. Rotation of the sleeve changes the profile of introduction of sweep gas, and can be used to optimize the performance of the module for each of a set of different pressure conditions.

What is claimed is: 1. In a gas-separation module, the module including a plurality of hollow fibers made of a material capable of separating components of a feed gas, the fibers defining a bore side and a shell side, the module having a length, the module including a conduit for the introduction of a sweep gas into the shell side of the module, the improvement comprising means for introducing the sweep gas at selected positions along the length of the module, wherein the introducing means comprises means for varying an amount of sweep gas introduced at different positions alone the length of the module, wherein the conduit includes perforations through which the sweep gas can flow, and wherein the introducing means comprises a sleeve having a plurality of slots, the sleeve being positioned within the conduit. 2. The improvement of claim 1, wherein the sleeve is rotatable within the conduit, wherein rotation of the sleeve selectively opens and closes a path for gas flow through the perforations in the conduit. 3. The improvement of claim 2, wherein the sleeve has a plurality of sets of slots, wherein each set comprises slots subtending an angle which varies from one set to another. 4. The improvement of claim 3, wherein the module defines an inlet end and an outlet end, wherein the sleeve has four sets of slots, the sets of slots being disposed along the sleeve from the inlet end to the outlet end, and wherein the sets of slots subtend smaller angles towards the outlet end and larger angles towards the inlet end. 5. A gas-separation module, comprising: a) a plurality of hollow fibers made of a material capable of separating components of a gas, the fibers being disposed between tube sheets located at an inlet end and an outlet end of the module, the fibers having a bore side and a shell side, b) a perforated conduit for introducing a sweep gas to the shell side of the fibers, and c) means for controlling longitudinal positions at which the sweep gas is introduced, wherein the controlling means also controls an amount of sweep gas introduced at different longitudinal positions alone the module, wherein the controlling means comprises a sleeve disposed within the perforated conduit, the sleeve comprising means for selectively blocking and unblocking selected perforations of the conduit. 6. The gas-separation module of claim 5, wherein the sleeve is rotatable within the conduit, and wherein the blocking and unblocking means comprises a plurality of slots formed in the sleeve. 7. The gas-separation module of claim 6, wherein the sleeve includes a plurality of sets of slots, the sets of slots being disposed along a length of the module, from the inlet end and extending towards the outlet end. 8. The gas-separation module of claim 7, wherein a number of slots formed in the sleeve is greater towards the inlet end, and is less towards the outlet end. 9. The gas-separation module of claim 8, wherein the sets of slots subtend progressively smaller angles as one moves from the inlet end towards the outlet end of the module. 10. The gas-separation module of claim 5, further comprising means for rotating the sleeve. 11. A method of operating a gas-separation membrane module, the module including a plurality of hollow fibers capable of separating components of a gas, the fibers defining a bore side and a shell side, the module including means for introducing a sweep gas into the shell side, the module having a length, the method comprising introducing a varying amount of sweep gas at a plurality of positions along the length of the module, wherein the introducing means comprises a perforated conduit, and wherein the introducing step comprises passing the sweep gas through a slotted sleeve disposed in a vicinity of the conduit, wherein portions of the slotted sleeve block and unblock perforations in the conduit. 12. The method of claim 11, further comprising rotating the slotted sleeve so as to change a profile of introduction of sweep gas into the module. 13. The method of claim 11, wherein the module has an inlet end and an outlet end, and wherein the method further comprises introducing more sweep gas near the inlet end than near the outlet end. 14. The method of claim 13, wherein the method comprises introducing a decreasing amount of sweep gas into the module, as one proceeds from the inlet end to the outlet end.
