Abstract: A gas separation module includes hollow polymeric fibers held between a pair of tubesheets. The tubesheets are mounted to a core tube, and the distance between the tubesheets is maintained constant. The core tube is formed in telescoping sections, such that the fibers are attached to the tubesheets when the core tube is in its extended position, and the core tube is then collapsed, forming slack in the fibers. The core tube includes two distinct channels, connected to receive permeate and retentate gas streams, and to carry these streams to outlet ports while keeping the streams separate. Because the tubesheets are affixed to the core tube, the tubesheets do not move under the influence of gas pressure in the module. The slack in the fibers compensates for shrinkage of the fibers, prolonging the life of the module.

Abstract: A gas separation membrane module includes hollow polymeric fibers held within a casing, the fibers being anchored by tubesheets at the ends of the casing. A filter material, preferably made of an activated carbon fiber fabric, is integral with the module, such that all gas entering the module must pass first through the filter before reaching the fibers. The filter may have the form of a circular pad affixed to one of the tubesheets. Alternatively, the filter could be a wrap disposed around the fibers, inside the casing. In another alternative, the filter could be provided within a core tube, in cases where a feed gas is introduced through the core of the module. In another embodiment, the filter could be provided in a separate unit from the gas separation module.

Abstract: A non-cryogenic system for producing high-purity nitrogen is connected to a coiled-tubing unit. The nitrogen is produced by passing compressed ambient air through two polymeric membrane modules connected in series. The output of the second module is a stream of high-purity nitrogen, which is conveyed into a coiled tube. The nitrogen can be used for inerting the interior of the tube, or the coiled tube can be inserted into an oil well, for delivering nitrogen into the well. The use of nitrogen in a coiled tube helps to prevent corrosion in the tube.

Abstract: A two-stage gas-separation membrane system includes two identical membrane modules held within a single casing. A feed gas is directed into the first module, so as to produce permeate and retentate streams. One of the latter streams then becomes the feed gas for the second module, and reaches the second module through a core tube located within the module. The product of the second module is the product gas for the system. The gas streams entering the two modules flow in mutually opposite directions. This arrangement makes it feasible to provide a two-stage system while using only the number of ports that would be needed for a single stage.

Abstract: A cartridge for non-cryogenically separating a gas into components includes a plurality of hollow polymeric fibers, the fibers being anchored by a pair of tubesheets, each tubesheet being adjacent to a head, the tubesheet and head being joined by a clamshell retainer. The cartridge does not have a core tube. The fibers are enclosed within a sleeve, the sleeve being sufficiently thin so as to be a non-structural element. The cartridge may be inserted within a larger pressure vessel. The cartridge of the present invention can accommodate more fibers than comparable cartridges of the prior art, and therefore has greater throughput.
