MPC Update Increases Air Liquide’s Efficiency and Profitability

Industrial gas leader adopts Yokogawa’s PACE tool for remote operations.

The Challenge

For many years, Air Liquide used multi-variable model predictive control (MPC) technology to optimize the performance of its air separation units.However, their legacy MPC software technology was outdated and not meeting value expectations. It was time to make a change and upgrade to the next-generation MPC technology.


Enter the Advanced Control and Estimation platform (PACE). Air Liquide selected this solution as their new MPC standard because it addresses many of the issues that were inherent in their legacy MPC software.

The Results

The PACE solution provided immediate tangible benefits. By limiting the need for excessive scripting while maximizing run time, it reduced engineering labor and maximized efficiency.
