Abstract: A gas separation membrane module includes a seal between a higher pressure gas and a lower pressure gas. The seal includes a compressible sealing member in between sealing surfaces. At least one of the sealing surfaces has corrosion-resistant cladding provided over either low alloy steel or high alloy steel. The cladding reduce the possibility of a seal failure due to corrosion of low alloy or high alloy steel exposed to acid gases or condensed moisture containing acid gases dissolved therein while at the same not requiring that all surfaces of the membrane module exposed to acid gases be provided with cladding.

Abstract: Parallel membrane elements are arranged in parallel within a pressure vessel. A sealing body is disposed within the pressure vessel and is compressed against an inner surface of the pressure vessel to provide a leak-right seal in between a feed gas side of the sealing body and a non-permeate side of the sealing body. The sealing body may be slid within the pressure vessel without damaging the sealing body and in all cases without requiring mechanical assistance.

Abstract: A method and system for providing nitrogen-enriched air (NEA) to aircraft fuel tanks using multiple air separation modules (ASMs). The ASMs employ membranes having different permeabilities and selectivities which are particularly selected to meet the varying NEA needs of the fuel tanks during flight.

Abstract: 1. An inerting system for a vented controlled atmosphere container, for inerting a flammable gas comprising a flammable vapor and oxygen, comprising: (i) a container; (ii) an outlet in the container for the flammable gas; (iii) a compressor, in fluid communication with the outlet, which compresses the flammable gas from the container; (iv) a separator, in fluid communication with the compressor, for removing oxygen from the flammable gas to produce an oxygen-depleted flammable gas; (v) an inlet in the container, which is in fluid communication with the separator; through which the oxygen-depleted flammable gas is fed into the container.
