Getting the most from your propane-propylene (PP) splitter unit

Precise cooling solutions that drive product yield

Propane-Propylene (PP) Splitters are crucial for transforming Refinery Grade Propylene (RGP) to Polymer Grade Propylene (PGP) by using thermocompression, PP Splitters upgrade the starting product RGP and can produce profitable outcomes.

When yield is key, the slightest temperature tweak can make the biggest difference. Utilizing cooling water as the source to lower overhead vapor temperatures, the propylene vapor can be condensed matching the PGP specification. Understanding this volatile process and affecting factors such as pressure, flow rates, composition of vapour and liquid streams is crucial.

Incorporating our expertise from the start

Success is based on having the correct vapor and liquid equilibrium from the start. Aggreko Process Services (APS) can fine tune this and advise on applying the cooling solution in the best way, sharing our expertise on introducing specific measurements of precisely how chilled water can deliver better product volumes.

Reviewing previous successful yields and analyzing seasonal variants allow us to ensure you achieve the most lucrative yield for your refinery.

In a recent project, we helped a refinery in the middle east increase its PP Splitter yield to 99.8%  —gaining them an additional USD 17 million in propylene revenue in just 120 days.

You can also read more on the challenges that face the modern refiners with PP splitters and applying the right cooling solution in our recent article by Massimo Capra, which was featured in November’s edition of Hydrocarbon Processing magazine.
