Case Study: Air Liquide achieves greater efficiency and profitability with Yokogawa’s PACE MPC upgrade

MPC Update Increases Air Liquide’s Efficiency and Profitability with Sustainable Benefits

Leading Gas Company faced the challenge of modernizing its legacy multi-variable model predictive control (MPC) software across air separation units while improving efficiency, supporting remote operations, and reducing reliance on time-consuming scripting and manual operator intervention. KBC A Yokogawa Company provided Yokogawa’s Platform for Advanced Control and Estimation (PACE) to replace the outdated MPC approach.

KBC A Yokogawa Company implemented PACE as the new MPC standard, improving control performance and making the applications more robust and sustainable. The upgrade reduced engineering labor, minimized operator interventions during steady-state operation and load changes, and increased production efficiency while supporting the customer’s broader remote operations and sustainability goals.
