Axens’ APC to Optimize SAMREF’s Prime-G+ Unit Performance
SAMREF (Saudi Aramco Mobil Refining Company) has selected Axens to evaluate, develop and implement an Advanced Process Control (APC) system for their Prime-G+ unit for the desulfurization of the FCC gasoline to ultralow sulfur content.The objective of the APC solution is to achieve substantial economic benefit by providing extremely precise control of product sulfur content while minimizing octane loss and reducing consumption of hydrogen and utilities.
This project has been managed by Axens’ APC experts in close collaboration with SAMREF engineers.
Axens’ experience in APC developments combined with their unique process licensor insight has enabled a rapid implementation of a turnkey solution with substantial quantifiable results.
Success relied on a proven methodology, tailored control strategy, inferential modules based on catalytic reaction kinetics resulting in a robust and easy to maintain process control solution.
While ensuring the tight low sulfur specification in the product, the APC application is generating a benefit of up to US $ 5.66 million per year.
SAMREF is an equally owned joint venture between Saudi Arabian Oil Company (Saudi Aramco) and Mobil Yanbu Refining Company Inc. (a wholly owned subsidiary of Exxon Mobil Corporation).
