Protected: Why Process Industries Need Causal AI, Not Just Predictive Maintenance

This article was originally posted on Chemical Engineering Online.
Summary
Because the post is protected, here’s a concise overview based on the title and topic: The argument is that process industries need causal AI in addition to predictive maintenance. While predictive maintenance forecasts failures from correlations, it often misses true root causes, struggles with shifting operating regimes, and can trigger false alarms. Causal AI models capture cause-and-effect across process variables and equipment, enabling root-cause diagnosis, “what-if” simulations, and prescriptive actions that improve reliability, yield, energy use, safety, and compliance. Effective adoption typically blends first-principles and data-driven models, encodes domain knowledge with SME input, emphasizes explainability for operator trust, and integrates with historians and control systems.

Where in your operations would understanding cause-and-effect deliver the biggest gains—asset reliability, quality stability, energy intensity, or emissions—and what data and SME input would you need to get started?

Without intervention data and solid state tagging, “causal” will just learn our sensor drift and hidden lineups. The only success I’ve had was tagging every control move, lineup change, and maintenance action, bumping a few valves in safe windows, mining startups and trips as natural experiments, and running it on-prem, air gapped from the PI historian. How does your approach handle that?
