Membrane Degasification

“HydroTech Engineering” Co Ltd facilitates the technology of gas removal from water with the help of hydrophobic membranes.

The Membrane Contactor design contains thousands of microporous hollow fibers knitted into an array that is tightly wound around a distribution tube with a central baffle. During operation, the liquid flows over the shellside (outer side) of the hollow fibers.

The patented Extra-Flow design incorporates a baffle in the middle of the contactor, which directs the liquid radially across the array. A strip gas or vacuum, either separately or in combination, is applied on the lumenside (inner side) of the hollow fibers. Because of its hydrophobic nature, the membrane acts as an inert support to allow intimate contact between a gas and liquid phase without dispersion. The gas/liquid interface is immobilized at the pore by applying a higher pressure to the liquid stream relative to the gas stream.
