Evonik introduces membrane technology for the separation of volatile organic compounds (VOCs)

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

Realize backward integration from raw material supply to production

Evonik is the only manufacturer of high-selectivity separation membranes in the world that realizes backward integration from raw material supply to production

PuraMem® VOC is specially designed for flexible integration into the infrastructure of existing systems

An innovative leader in separation membrane technology

"PuraMem® VOC strengthens Evonik's position as an innovation driver in membrane separation of volatile substances and membrane separation technologies for liquids

Evonik launched its first separation membrane product, SEPURAN® Green separation membrane for biogas purification, in 2011, laying the foundation for the development of the separation membrane business
