How Propylene Splitter (C3 Splitter) Works - phxequip.com
Explore the vital role of propylene splitters in the petrochemical industry with this guide on modern separation techniques for high-purity propylene (C3H6) from propane (C3H8). Discover advanced methods, including heat-integrated distillation, membranes, adsorptive separation, and cryogenics, that improve efficiency and lower energy demands.
This design guideline reviews the basic elements of propylene splitter fractionators in sufficient detail to allow an operations personnel or engineer to review the design a propylene splitter. This Guideline covers the sizing of tower diameter, tray spacing, reflux ratio, down comer sizing, and number of stages.
Propylene Splitters will have sub-cooled reflux return or a sub-cooled feed. The performance of a C3 Splitter tower is heavily dependent on a proper heat balance on the tower. Sub-cooled streams have to be accounted for properly. Propylene pure component liquid specific heat data is quite varied. The variation
Distillation Optimization By Vapor Recompression
Mar 1, 2012 · This article illustrates the technique through an example of a typical C3 splitter design wherein significant energy savings and operational benefits are achieved by using vapor recompression distillation.

multi-downcomer tray design is the best solution for C3 splitters. With the expansion of production throughput, the diameters of new C3 splitters are becoming larger and it is becoming more common to change from two-pass and four-pass trays …
Troubleshooting a C3 splitter tower Part 1: evaluation
The PetroLogistics giant C 3 splitter (see Figures 1 and 2) is a heat-pumped, 28ft (8.5m) internal diameter tower operating at 105 psig at the top. The tower contains four-pass, equal-bubbling-area fixed valve trays with mod-arc downcomers (MOAD) on the outside panels.
Optimized tray designs were used in the splitters covered in the case studies, yielding tray efficiencies of 90 – 100%. These high efficiencies have been used to achieve combinations of the following benefits: o Reducing the number of trays, which would reduce the tower height. o For a fixed number of trays, the reflux can be reduced.

Propane-propylene mixture splitting by industrial conventional rectification incorporating a heat pump for energy intensity decrease was modeled in the Matlab environment. The constructed model was verified by comparing its results with operational data of a real C3 fraction splitting unit.
C3 fraction splitting can be characterized by high energy demand as the propylene-propane mixture is a close boiling mixture (Demirel, 2004). Pro-pylene polymerization to which the produced propylene is submitted requires high purity pro-pylene (> 99.6 %). To achieve this via conventional approach, numerous equilibrium stages and high
