How it works
The robust Permylene membrane technology results in high separation performance that delivers polymer-grade olefins. The composition of the Permylene membrane allows ethylene, propylene and other olefins to chemically interact with it, facilitating olefin transport across it while rejecting paraffins and other constituents.
Permylene uses a natural source polymer facilitated transport membrane designed for industrial conditions.
Steady and stable olefin transport is achieved in continuous, non-stop operation via circulation of an aqueous silver nitrate solution over a spiral wound membrane containing a hydrogel coating.
- The silver ions in the silver nitrate solution within the hydrogel structure form a reversible complex with the double bonds of the olefin molecules
- Any molecules not possessing a double bond are rejected, resulting in excellent selectivity
- The process is primarily driven by the olefin partial pressure differential across the Permylene membrane resulting in commercially attractive permeation rates
