Gasses: Hydrocarbons and Other Process Gasses

A substantial amount of the total global energy consumption is due to hydrocarbon purification processes. Olefin/paraffin (O/P) separation, used for propylene or ethylene purification, are amongst most energy-demanding separation processes. UniSieve membrane add-on units enable highly efficient hydrocarbon purification by increasing process-energy savings, maximizing product recovery, and reducing process CO2 emissions. 

Application Examples:

  • 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 the 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. 


Applications Examples:

  • Biogas purification (methane purification)

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

Gasses: Hydrogen, Carbon Monoxide, 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.
