EXAMPLEs of Applications for Permylene Membranes
Membrane separation of C4
The following provides a typical C4 application whereby two valuable streams are separated using a Permylene membrane system, whereby this would normally be considered difficult and costly if not impractical.
Olefins Recovery from Purge Streams
The following is a typical polypropylene system with a purge stream to remove contaminants that would otherwise have a drastic effect on downstream performance and production. This stream also contains valuable olefins that, if they could be extracted from paraffins and other components, would be extremely attractive. In some applications these waste streams are flared adding to GHG/VOC/CAC emissions or fed back upstream of the process sometimes causing further operational challenges.
- Olefin recovery to high purity specification – over 90% recovery depending on application/conditions
- Reduction in flaring/emissions or upstream recycling
