Axens’ APC to Optimize SATORP Aromatics Complex Performance

Share this article

SATORP (Saudi Aramco Total Refining and Petrochemicals Company) has selected Axens to evaluate, develop, and implement an Advanced Process Control (APC) system for its aromatics complex ParamaX® producing high purity Paraxylene and benzene. The objective of the APC system is to achieve substantial economic benefit by providing extremely precise control of product quality while reducing consumption of utilities.

This project is managed by Axens’ APC experts in close collaboration with SATORP engineers to develop the first process control solution for the whole aromatic complex including Eluxyl® Axens’ technology. Eluxyl® is at the heart of the ParamaX Suite and is known for its excellence in operation, ability to handle high-capacities, and highly-stable molecular sieve for Paraxylene separation. The other aromatics process technologies, parts of the ParamaX Suite are the xylenes isomerization unit, XymaxSM, developed by ExxonMobil Chemical Technology Licensing and the extractive distillation unit, Morphylane®, by ThyssenKrupp Uhde Engineering Services.

Axens’ APC project execution can rely on a proven methodology, tailored control strategy, inferential modules based on catalytic reaction kinetics and a unique process licensor insight resulting in a robust and easy to maintain process control solution.
