: Second Stage Gasoline Hydrogenation Unit
: Axens C5+ Pygas Hydrogenation
Short Name: GHU-2
Description: 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. This Process consists in Olefins and Sulfur removal from all or a specific Fraction of the First Stage Effluent. The complete removal of Olefins and Sulfur has to be ensured while minimizing Aromatics Hydrogenation. The Effluent is then routed to an Aromatics Recovery Unit.
