Innovation leader in membrane-based separation technology
Evonik, a specialty chemicals company from Germany with more than 32,000 employees working together in more than 100 countries, is one of the world innovation leaders in membrane-based separation technology.
We boost the chemistry of high-performance polymers into highly efficient membranes for gas separation, organic solvent nanofiltration (OSN) and for separation of volatile organic compounds (VOCs).
SEPURAN® Green membranes for biogas upgrading
SEPURAN® N2 membranes for nitrogen generation
SEPURAN® Nobel membranes for helium recovery
SEPURAN® Nobel membranes for hydrogen generation
SEPURAN® NG membranes for natural gas processing
PURAMEM® / DURAMEM® membranes for organic solvent nanofiltration (OSN)
PURAMEM® VOC membranes for volatile organic compounds separation (VOCs)
LEADING INNOVATION DUE TO FULLY BACKWARD INTEGRATION
Evonik is the world’s only fully backward-integrated producer of high-selectivity separation membranes. Thanks to the group's many years of expertise in polymer chemistry, Evonik is able to adjust the membrane properties already at the development stage of the base material—the high-performance polymer—to produce especially selective and robust membranes that can withstand extreme pressures and temperatures.
