Evonik, the world's leading specialty chemical company, is expanding its separation membrane business, developing a membrane technology for the separation of volatile organic compounds (VOCs) and bringing it to market under the PuraMem® VOC brand
PuraMem® VOC is a new polymer-based membrane technology that efficiently separates long-chain hydrocarbons from natural gas or nitrogen mixtures
PuraMem® VOC separates the gas mixture according to the molecular size of the substances to be separated: the gas mixture can pass through the separation membrane at a pressure of up to 80 bar, the larger VOC molecules pass through the separation membrane, and the smaller gas molecules are retained
