Technology

Lummus CATOFIN Technology uses Fixed-Bed reactors and a Chromium-based Catalyst. In the Reaction and Regeneration Section Fresh Propane feed is mixed with Recycled Propane from a Propylene-Propane Splitter. This Stream goes to a De-Oiler for Impurities Removal and then is carried to the Reaction step, which is Continuous and operates in Cycles. In this step, multiple Parallel Reactors undergo a controlled sequence of Reaction, Catalyst Reduction and Catalyst Regeneration. In the Product Recovery Section there is a Low-Temperature Separation Unit, the objective of which is to separate Hydrogen and Light Byproducts generated in the Reaction step from the Main Product. The Hydrogen-rich Stream is then sent to a Pressure-Swing Adsorption (PSA) unit. The Liquid Stream generated in the Low-Temperature Separation is fed to Distillation Facilities consisting of a De-Ethanizer and a Propylene-Propane splitter for Product Recovery.
