Can Permylene membrane systems be used to separate mixed C4 (butenes/butanes) streams?
Yes. C4 hydrocarbon separations (butenes from butanes) are particularly challenging for distillation due to the boiling point similarity between the C4 species. This makes C4 separations such as 1-butene/iso-butane and 2-butene/n-butane difficult. Permylene’s facilitated transport separation mechanism functions independent of relative volatility, allowing these separations to be easily achieved. Permylene membrane separation technology can replace and/or integrate with traditional C4 distillation and result in a more cost effective and operationally efficient system.
