Unconventional improvement of propylene recovery yield at the PP splitter

Thermocompression-equipped propane-propylene (PP) splitters are used to upgrade large quantities of refinery-grade propylene (RGP) to polymer-grade propylene (PGP).

Thermocompression-equipped propane-propylene (PP) splitters are used to upgrade large quantities of refinery-grade propylene (RGP) to polymer-grade propylene (PGP). This configuration does not rely on reboiling heating mediums, and it relies very little on utilities conditions—yet, deterioration of the cooling water temperature is the cause of lower propylene recovery yield. The following case study includes process conditions, recovery yield, final setup and economic evaluation of a condensation improvement project for rent that exploited industrial refrigeration equipment (mobile chillers) applied to distillation (i.e., PP splitters). In crude oil refineries, propylene is obtained as a b
