This Hydrocarbon Processing special focus article explores the deployment of cutting edge catalytic technologies in a modern, large scale aromatics complex, highlighting how advanced process integration and catalyst innovation can significantly improve energy efficiency, product yields and overall plant economics. Drawing on the successful commissioning and operation of a state of the art aromatics complex in China, the article details key technologies for aromatics transalkylation, vapor phase xylenes isomerization, PX purification and selective hydrogenation, and explains how their combined implementation enables high paraxylene recovery with minimal aromatics loss and reduced environmental footprint.
The article is co authored by J. Cao (ExxonMobil Product Solutions), Thierry Leflour (Axens), and M. Ding (CNOOC Huizhou Petrochemical Co. Ltd.), and provides valuable technical insights for refiners and petrochemical producers seeking to optimize aromatics production in highly competitive markets.
