The instant application relates to a high pressure spiral-type hollow fiber membrane fabric-containing module or contactor, comprising: a high pressure module housing or vessel; a pair of end caps; liquid end ports and at least one gas port; and at least one membrane cartridge, wherein each module or contactor has one or more shims, spacers, protrusions, and/or the like on a cartridge shell exterior, on a module housing interior, on the cartridge shell exterior and on the module housing interior, and/or between the shell and the housing.

Contactors, cartridges, components, systems, and related methods

In at least certain embodiments, the present invention is directed to contactors, modules, components, systems, and/or methods of manufacture, and/or methods of use including degassing liquids. In at least particular possibly preferred embodiments, the contactor or module is integrally potted, has planar, disc shaped end caps, and a cylindrical housing or shell receiving and supporting a membrane structure. In at least particular possibly preferred embodiments, each of the planar disc shaped end caps has a central opening therein adapted to receive a liquid end port or nozzle, another opening therein adapted to receive a gas end port or threaded pipe, and is held in place in the housing or shell by at least one retaining element such as a retaining or locking ring. In at least particular possibly preferred embodiments, the integrally potted membrane structure is potted in place in the housing or shell by an inverted potting process involving the use of a removable plunger or plug to recess the potting.
