Medarray, Inc. recently released its newest PermSelect Silicone Hollow Fiber Membrane module. The PDMSXA-1.0 is sized for medium flow rate applications, ranging from 0.5 to 6.0 l/min with a membrane surface area of 1.0 meter square, based of fiber OD. Using a proprietary forming process, the company creates self-supporting silicone (PDMS) hollow fibers with an outside diameter of only 300 microns, and wall thickness of only 55 microns. The 1 m2 module joins Medarray's commercially available 10cm2, 0.25m2, 0.75m2, and 2.1m2.
The silicone permeable membrane separates gases and vapors based on permeability differences - not on pore size‚ - allowing it to perform challenging separations from mixed gases or gases dissolved in liquids. Because the silicone hollow fibers are dense (non-porous), the risk of fouling is minimized and there is no possibility of pore wetting. "This makes the PermSelect membrane contactors ideal for liquid contacting applications, such as degassing and gassing liquids including low surface tension liquids" Noted Jake Nikolic, Senior Product Manager. "The new module is also ideal for gas separations and pervaporation, including air humidification and dehumidification, oxygen enrichment, nitrogen enrichment, methane purification, CO2 capture, VOC removal and recovery, membrane distillation of water, and pervaporation of alcohols".
