Example 1:

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.

Butene Production Imtex Membrane Separation

Example 2:

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
