Axens Delivers Optimization Software to Aromatics Oman for its ParamaX™ Complex

The POS integrates all units of the complex. The simulations are based on PRO/II® comprehensive steady-state process simulation software developed by Invensys Operations Management. They are enhanced by the use of accurate proprietary models for reactions and paraxylene adsorption. It allows plant engineers to perform whatif studies and to optimize operating costs taking into account variations in feed characteristics, feed and utility costs, and final product prices. It is intensively used by AOL for determining the most suitable naphtha feedstock allowing operation of the complex in the more profitable conditions.

The ParamaX Technology Suite implemented in Oman is composed of the following processes:

• Naphtha hydrotreating - for feedstock purification
• Aromizing™ - continuous catalyst regenerative (CCR) reforming for aromatics production from naphtha
• Morphylane® - aromatics extractive distillation
• Eluxyl® - high-purity paraxylene separation from mixed C₈ aromatics
• XyMax^SM - C₈ aromatics isomerization with ethylbenzene dealkylation
• TransPlus^SM - toluene and C₉+ aromatics transalkylation to produce C8 aromatics.

Uhde is in charge of the basic engineering for the Morphylane process, while Axens ensures basic engineering for the other ParamaX™ technologies as well as the integrated package.
