  • Hollow-fiber membrane casting solution additive for rapid solvent removal
    Patent number: 8641807
    Abstract: Hollow fiber membranes, such as those used in air separation modules, are generally made from solution spinning. Typically, solvent is present in the bore of the fiber for the spinning process. This solvent, in addition to the solvent already present in the polymer casting solution, may cause voids in the fiber material. By adding a polycarboxylic acid to the polymer casting material, these voids may be reduced or eliminated.
    Type: Grant
    Filed: January 31, 2011
    Date of Patent: February 4, 2014
    Assignee: Honeywell International Inc.

  • AIR SEPARATION MODULE FIBER MATERIAL FORMULATION
    Publication number: 20110146492
    Abstract: Hollow fiber membranes, such as those used in air separation modules, are generally made from solution spinning. Typically, solvent is present in the bore of the fiber for the spinning process. This solvent, in addition to the solvent already present in the polymer dope solution, may cause voids in the fiber material. By adding citric acid to the polymer dope material, these voids may be reduced or eliminated.
