Membrane contactors for liquid degassing    Membrane degassing systems     Europe, Middle East and Africa    North and South America     Asia Pacific Membrana-Charlotte - www.liquicel.com - 13800 South Lakes Drive, Charlotte, NC 28273, USA email, Tel. company profile: The Quality Management System of the Charlotte, NC, manufacturing facility was ISO Registered to ISO 9001:2000 in 2002. On March 1, 2002, the parent company of Celgard LLC purchased Membrana GmbH in Wuppertal, Germany. With this purchase, Membrana was combined with the Liqui-Cel® Membrane Contactor and Hollow Fiber businesses of Celgard LLC. On August 1, 2002, the Liqui-Cel® business line adopted the new company name of Membrana. Products:   Liqui-Cel® Membrane Contactors They are used for degassing liquids around the world. They are widely used for O2 removal from water as well as CO2 removal from water. They have displaced the vacuum tower, forced draft deaerator, and oxygen scavengers around the world for over 10 years. Liqui-Cel®, SuperPhobic® and MiniModule® Membrane Contactors are used extensively for deaeration of liquids in the microelectronics, pharmaceutical, power, food & beverage, industrial, photographic, ink and analytical markets. Compact Membrane Systems, Inc. - www.compactmembrane.com - 325 Water Street, Wilmington, DE 19804, USA email, Tel. company profile: Compact Membrane Systems, Inc. was founded in 1993 by Stuart Nemser after acquiring exclusive rights to certain DuPont patents and fluoropolymers. CMS today has a growing patent portfolio due to a successful track record of obtaining research grants. Compact Membrane Systems' focus is on the research, development and commercialization of membranes and thin films composed of fluorinated polymers with exceptional gas transport properties and chemical resistance. Applications where CMS technology is used fall into two general categories: membrane cartridges for gas separation and membrane contactors for the introduction or removal of gases from liquids. Products:   Degasification of Mineral Oils: Removal of dissolved gases through CMS membrane contactors allows automated condition monitoring of dielectric oil by the electric power industry to avoid catastrophic failure of large and aging electric transformers in the power grid. Ozonation of Water: Chemically resistant CMS membrane contactor for bubbleless ozonation of water. Ozone is injected into ultra-pure process water for final purification at the point-of-use in semiconductor plants. Conventional injectors are unsuitable for semiconductor fluids, as gas bubbles in semiconductor fluids are known to decrease yield of saleable chips. Other Contactor Applications: CMS membrane contactors suitable for other demanding applications are currently under development for bulk gasification and degasification of difficult-to-process low surface tension liquids, e.g. surfactant solutions, oils, inks, solvents, etchants, beverages, pharmaceutical and bioreactor solutions.     www.membrane-guide.com     Keywords
