Permylene™ Facilitated Transport Membrane Technology

Beyond Distillation: Electrified Olefin Separation for a Low-Carbon Future

Permylene™ uses facilitated transport — mobile silver ions inside a patented hydrogel membrane — to pull olefins out of a mixed gas stream at near-ambient temperature. Distillation does olefin separation with fossil fuels, Permylene™ does it with electricity.

Distillation does olefin separation with fossil fuels, Permylene™ does it with electricity.

Electrification

Facilitated transport is entirely electricity-driven. Distillation does olefin separation with fossil fuels, Permylene™ does it with power.

No combustion
Zero fuel burned on site
No steam
No boiler, no reboiler duty
No thermal cycling
Near-ambient temperature operation

Technology

Bond. Absorb. Diffuse. Desorb.

Mobile silver ions inside the membrane bond to the olefin's double bond, carry it across, and release it on the low-pressure side. Paraffins never make the trip.

How facilitated transport replaces thermal separation, step by step — and how it compares to distillation and conventional membranes.

The Big Three Markets

See all five applications →

Three places in the olefin value chain where Permylene™ already changes the economics.

C4 Olefin Extraction

Separating butene from raffinate mixed streams at polymer-grade purity.

C3 Splitting

Debottlenecking propylene/propane separation without adding another distillation column.

Polyolefin Vent/Purge Gas

Recovering olefins from vent and purge streams that would otherwise be flared or burned as fuel gas.
