Gas separation modules and methods for forming

摘要

A gas separation module includes at least one inlet port, a plurality of outlet ports, and a plurality of hollow fiber membranes. Individual fibers have a feed end and a product end with a retentate interior side and a permeate exterior side. The module includes a feed tubesheet within the shell segregating the at least one inlet port and the permeate side of the fibers. The feed tubesheet includes a matrix and at least one segment joint. The segment joint separates segments of the feed tubesheet from one another. A formation method includes positioning a hollow fiber membrane material in association with at least one tubesheet segment joint and applying a matrix. The method includes forming a feed tubesheet from cured matrix and the segment joint and forming a plurality of hollow fiber membranes from the fiber material. The segment joint separates segments of the feed tubesheet from one another.

1. A gas separation module formation method comprising:
positioning a hollow fiber membrane material in association with at least one tubesheet segment joint; applying a matrix to the hollow fiber membrane material and to the segment joint and curing the matrix, the at least one tubesheet segment joint containing a compliance material different from the matrix; forming a feed tubesheet from the cured matrix and the at least one tubesheet segment joint; and forming a plurality of hollow fiber membranes from the hollow fiber membrane material, individual fibers having a feed end and a product end, the cured matrix encapsulating the feed end of the fibers, the feed tubesheet securing the feed end of the fibers, and the at least one tubesheet segment joint separating a plurality of segments of the feed tubesheet from one another; and applying a thermoplastic veil between layers of the plurality of hollow fiber membranes, the thermoplastic veil containing a material different from the matrix and increasing toughness of the feed tubesheet.
