Technology

In order to recover BTX from Pygas, the Unsaturated Compounds and sulfur Compounds have to be removed efficiently. This is the target of Axens’ two different Stages of Pygas Hydrogenation : GHU-1 and GHU-2. The First Stage of the Gasoline Hydrogenation Unit (GHU-1) involves the selective Hydrogenation of Diolefins and Styrenics. Efficiency of the Conversion in this Stage is essential for the downstream Unit’s operation. In the Second Stage of Pygas Hydrogenation (GHU-2) the C₆-C₈ Heart Cut is further processed to prepare a Feedstock suitable for Aromatics Recovery, by selectively Hydrogenating the Olefins and Hydrodesulfurization.
