A contactor system includes a plurality of contactor panels. Each contactor panel includes a frame member and a membrane array adapted to be received within the frame member. The membrane array defines a first end portion, a second end portion, and a plurality of hollow fibers. The contactor system also includes a first manifold in selective fluid communication with the first end portion of the membrane array of each contactor panel. The contactor system further includes a second manifold in direct fluid communication with the second end portion of the membrane array of each contactor panel. The contactor system includes a controller configured to provide selective fluid communication between the first manifold and the first end portion of the membrane array of each contactor panel.

Contactor system and method of operating contactor system

Porous membrane contactors and/or their methods of manufacture and/or use are provided. In at least selected embodiments, the present invention is directed to flat panel hollow fiber or flat sheet membrane contactors and/or their methods of manufacture and/or use. In at least certain particular embodiments, the present invention is directed to hollow fiber array flat panel contactors, contactor systems, and/or their methods of manufacture and/or use. In at least particular possibly preferred embodiments, the contactor is adapted for placement in an air duct (such as an HVAC ductwork) and has a rectangular frame or housing enclosing at least one wound hollow fiber array or membrane bundle.

Flat panel contactors and methods

In accordance with at least selected embodiments of the present invention, an improved liquid degassing membrane contactor or module includes a high pressure housing and at least one degassing cartridge therein. It may be preferred that the high pressure housing is a standard, ASME certified, reverse osmosis (RO) or water purification pressure housing or vessel (made of, for example, polypropylene, polycarbonate, stainless steel, corrosion resistant filament wound fiberglass reinforced epoxy tubing, with pressure ratings of for example, 150, 250, 300, 400, or 600 psi, and with, for example 4 or 6 ports, and an end cap at each end) and that the degassing cartridge is a self-contained, hollow-fiber membrane cartridge adapted to fit in the RO high pressure housing.

High pressure liquid degassing membrane contactors and methods of manufacturing and use

In accordance with at least selected embodiments of the present invention, an improved liquid degassing membrane contactor or module includes a high pressure housing and at least one degassing cartridge therein. It may be preferred that the high pressure housing is a standard, ASME certified, reverse osmosis (RO) or water purification pressure housing or vessel (made of, for example, polypropylene, polycarbonate, stainless steel, corrosion resistant filament wound fiberglass reinforced epoxy tubing, with pressure ratings of, for example, 150, 250, 300, 400, or 600 psi, and with, for example 4 or 6 ports, and an end cap at each end) and that the degassing cartridge is a self-contained, hollow-fiber membrane cartridge adapted to fit in the RO high pressure housing.

A wafer-shaped hollow fiber module adapted for in-line use in a piping system. The piping system may include two standard bolted flange connections, and at least one wafer-shaped hollow fiber module sealed between the two standard bolted flange connections. The wafer shaped hollow fiber module includes: a cylindrical housing having an open end and a closed end having a first sealing surface and an inlet port; at least one side port through the cylindrical housing; an end cap united to the open end having a second sealing surface and an outlet port.

A contained liquid membrane contactor includes a perforated center tube, first and second membrane mats each with a first and a second end both being open, four tube sheets affixing the membrane mats to the center tube, a shell sealed to the tube sheets, and two end caps. The first end of the first mat extends a first distance beyond the second end of the second mat. The first end of the first mat is open at the first tube sheet while the first end of the second mat is open at the second tube sheet. The second end of the first mat is between the second and fourth tube sheets and the second end of the second mat is between the first and third tube sheets.

Contained liquid membrane contactor and a method of manufacturing the same

The instant invention is a hollow fiber membrane contactor. The hollow fiber membrane contactor includes a cartridge, a shell, a first end cap, and a second end cap. The shell, which is adapted for enclosing the cartridge, has two ends and an opening. The cartridge further includes a perforated center tube, a hollow fiber fabric, a first tube sheet, a second tube sheet, and a plug. The perforated center tube has a first end and a second end, and the hollow fiber fabric surrounds the center tube. The hollow fiber fabric includes hollow fiber membranes, and each hollow fiber membrane has a lumen. A first tube sheet and a second tube sheet affixes said fabric to said center tube at each end of the center tube, and the plug is located at the first tube sheet. Hollow fiber lumens are open at the first tube sheet and hollow fiber lumens are closed at the second tube sheet. The first end cap and the first tube sheet define a first headspace therebetween. The first end cap has an opening therethrough, which is in communication with hollow fiber lumens via said first headspace. The second end cap has an opening, and it is in communication with the center tube.

Three-port high performance mini hollow fiber membrane contactor

The present invention is directed to a membrane contactor for debubbling (or degassing) a liguid. The membrane contactor comprises a perforated core tube, a plurality of hollow fiber membranes surrounding the tubes and having an end, a tube sheet affixing the end of the plurality of hollow fiber membranes to the core tube, and a shell surrounding the plurality of hollow fiber membranes and the tube sheet. A lumen side is defined by an internal surface of the membranes. A shell side is defined by the perforated core tube, an external surface of said membrane, and the shell. The membrane is a single layered, skinned, polymethylpentene hollow fiber microporous membrane. The skin is on the shell side.

Contactor for debubbling an ink

The present invention is directed to a contactor for degrassing a liquid. The contractor includes a perforated core and a microporous membrane fabric wrapped around the core. The fabric includes a polymethyl pentene hollow fiber as a weft fiber and a warp yarn. A tube sheet secures the ends of the wound fiber and a shell encases the tube sheet and fabric. The shell has at least one opening to permit fluid flow through the shell and an end cap. In a further embodiment the invention is directed to a contactor for degrassing a liquid wherein the contactor is adapted to withstand pressures greater than 0.4 MPa and temperatures greater than 50&deg; C.
