A gas separation module and assembly for housing ceramic tubular membranes. The module includes a plurality of tubes containing the ceramic tubular membranes. The tubes are arranged parallel to one another and are supported by tube sheet plates at each end. Gas-tight seals surround each membrane, preventing a permeate gas within the inner lumen of the membrane from mixing with a feed or residue gas in the tube interior. The module also contains a gas distribution pipe for introducing feed gas into, and withdrawing residue out of, the module. This configuration allows for ceramic tubular membranes to be modularized for use in an assembly that carries out many types of gas separations.

In a hollow fiber membrane module including a housing case, potting material loaded into the housing case, a cap attached to each of both ends of the housing case, and an O-ring closely held by the potting material and the cap, a whole area of the O-ring between a first contact point and a second contact point is exposed when the area is viewed from a central axis passing through a center of the ring shape of the O-ring, the first contact point being a point of contact between the O-ring and the cap, which faces inner cavity defined by an end surface of the potting material facing the cap, an inner circumferential surface of the O-ring and an inner circumferential surface of the cap, and the second contact point being a point of contact between the O-ring and the potting material, which faces the inner cavity.

This invention concerns a method for desalination of sea water and a design and construction of a centrifugal filter for desalination of water. The process uses the filter developed based on reverse osmosis technology as a fundamental component that uses hollow fiber membrane modules arranged in a spiral manner around a central support pipe and distributed in concentric rings around the periphery of the rotating section to favor the formation of Dean vortices. Wherein the membrane is built with a structure of an aromatic polyamide as the first layer, followed by a layer of polyestersulfone and a support layer of polyester; applying the material Kevlar 49 in position 1 and 4 on the aromatic chain structure to increase the structure and resistance of the membrane.

A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.

An air separation module includes a housing, an air separation element, and an insulating element. The housing has an inlet and two outlets. The air separation element is enclosed within the housing and extends along a length of the housing. The insulating element is positioned inward of an outer perimeter of the housing and substantially surrounds an outer perimeter of the air separation element along a length of the air separation element.

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.

An artificial lung device includes: a housing which is formed in a tubular shape including both end portions closed, includes a blood inflow port and a blood outflow port, and is arranged such that a center axis of the housing is directed in a lateral direction; a hollow fiber body (gas exchanger) which is arranged in the housing and performs gas exchange with respect to blood while the blood flows from the blood inflow port to the blood outflow port; and a straightening frame (gas guide portion) by which a gas having flowed through the gas exchanger by the flow of the blood is guided to the gas exchanger again in the housing.
