The present invention relates to units for separation of gas mixtures using hollow fiber membranes and may be used in chemical, oil, gas and other industries. More specifically, this invention relates to the structure of the membrane gas separation module which may be applied, for instance, in membrane separation units for helium concentrate. The membrane gas separation module comprises the horizontal body with end covers and membrane cartridges made of a bundle of hollow fibers and located in an inversed manner in relation to the center. The body comprises symmetrical end sections of large diameter which are mated by conical transition sections with the central section of minor diameter. In this case length of end sections corresponds with length restricted by the body end and input area of membrane cartridges, and central section inner diameter is configured to provide both free mounting/dismounting of membrane cartridges and tight fit thereof at the sealing point with ring gaskets. Feed gas input nozzles are located on end sections of the body perpendicularly to its longitudinal axis in front of input areas of membrane cartridges, permeate output nozzles are located on end sections of the body near end covers perpendicularly to the body longitudinal axis. The technical result is reduction of weight and dimensional properties of the membrane module and the whole gas separation unit in general, as well as reduction of labor intensity of operations during mounting/dismounting of body end covers of the membrane module.

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.

A membrane separation apparatus includes: a lower support body that includes a water-to-be-treated introduction port and a concentrated water discharge port; an upper support body that includes a permeated water discharge port; a separation membrane that is provided between the lower support body and the upper support body, and that separates water to be treated into permeated water and concentrated water; and a first sheet-like elastic member that is provided between the separation membrane and the lower support body, and that forms seals between the separation membrane and the lower support body and between the lower support body and the upper support body.

Disclosed is a spiral wound membrane element that provides two permeate streams through a permeate carrier sheet. The spiral wound membrane element is sealed such that the only communication with the permeate carrier is through a membrane sleeve. The first permeate stream flows spirally inward and the second permeate stream flows in the opposite direction, spirally outward. The permeate carrier sheet is sealed at two edges so that the permeate streams can only discharge from opposite, unsealed edges of the permeate carrier sheet. The first permeate stream may be collected in a central collection tube and the second permeate stream may be collected in a peripheral region of the membrane element.

The present invention relates to a humidifier for a fuel cell, the humidifier comprising: a humidifying module for humidifying a dry gas, supplied from the outside, by using a wet gas discharged from a fuel cell stack; and a first cap coupled to one end of the humidifying module. The humidifying module includes: a mid-case; and at least one cartridge disposed in the mid-case and accommodating a plurality of hollow fiber membranes. The humidifier for a fuel cell further includes a first packing member which is air-tightly coupled to at least one end of the humidifying module through mechanical assembly so that the first cap is in fluid communication with only the hollow fiber membranes.

In once aspect, the present disclosure relates to a liquid diversion apparatus comprising: an attachment module comprising: an attachment module housing, a first connecting portion configured to connect to a portion of an apparatus configured to direct liquid, and a second connecting portion configured to connect a downstream portion of the attachment module housing to a receptacle module; a first sealing portion configured to seal a porous plate module and the attachment module; the porous plate module comprising: a first filtering portion, a second filtering portion configured to connect to the first filtering portion, and a third filtering portion configured to connect to the second filtering portion; a second sealing portion configured to seal the porous plate module and the receptacle module; and the receptacle module configured to perform the following: secure to the attachment module, and collect liquid diverted through the porous plate module.
