Olefin/paraffin (O/P) separation is one of the most energy-demanding separation processes due to similar chemical properties within olefin/paraffin pairs (e.g. propylene/propane, also known as C3 molecules). Fortunately, the small size-difference between propylene and propane permits molecular sieving via UniSieve membranes, leading to process-energy savings, increased product recovery, and a reduction in CO2 emissions. Furthermore, our membranes enable low-temperature and low-pressure separation of O/P.


Propylene purification (C3 Splitter Hybrid / C3 splitter replacement)

Propylene recycling (flare gas, polypropylene reactors)

Gasses: Hydrogen, Methane, Carbon dioxide

Biogas is produced from the decomposition of organic waste. Before biogas is fed into the gas grid it has to be upgraded. Regardless of production scale and process of the biogas, its purification accounts for a major fraction of the product cost and overall energy-efficiency. 

UniSieve provides the latest membranes for making your biogas or biomethane even more sustainable. 



  • Biogas purification (methane purification)

  • Power-to-gas separation upgrade (hydrogen recycling, methane purification)

Gasses: Hydrogen, Carbomonoxide, Carbondioxide, Nitrogen, Oxygen, Noble Gasses

The excellent versatility of MOF-membranes allow for advanced gas sensing. By low pressure separation of gasses prior to sensing, the challenges of selectivity can be avoided. Poisoning could be reduced and sensor lifetime prolonged. Applicable in high value, robust and highly sensitive devices.

Gasses: Hydrogen, Methane, Carbondioxide, Nitrogen, Oxygen, NOx

Space technology requires modular, reliable and light separation solutions for in situ resource utilization (ISRU) on extraterrestrial ground or atmosphere revitalization systems (ARS) on the ISS space station. MOF-membranes can be operated at low pressures and the required selectivity and flow can be fine-tuned according to the application.

Liquids: Water, Ethanol, Methanol, Various Organic Solvents

By choosing the right molecular sieve and and a fitting polymer, efficient and durable membranes for specific liquid separations can be obtained. Possible applications of UniSieve membranes in the liquid-liquid separation area are in pervaporation, water treatment and organic solvent dehydration.
