Abstract
Improved processes for the separation of olefins from paraffins, such as propylene from propane are provided. Two product splitters are used in parallel to separate propylene from propane. One of the product splitters operates at a lower pressure, while the second product splitter operates at a higher pressure. The use of the two splitters in parallel provides a process for recovery of a high purity propylene product with lower energy consumption compared to prior art processes.
