Top 4 PID Tuning Mistakes – and How to Avoid Them with SIMCET

Imagine driving a car where the accelerator responds too slowly, the brakes overreact, and the steering wheel constantly oscillates left and right. You would never feel comfortable or safe. In industrial process control, poorly tuned PID loops behave in a similar unstable and unpredictable manner. Instead of delivering a smooth and well-controlled system, the control […]

From Raw Material Variability to Non-linear Process Gain: How Auto-Adaptive Control Systems Cope

Industrial processes rarely behave as textbook models suggest. Raw materials arrive with varying compositions, ambient conditions fluctuate, equipment degrades, and operating points shift. Traditional fixed-parameter PID controllers designed for "average" conditions struggle to maintain optimal performance across these varying scenarios. Auto-adaptive control systems address this fundamental challenge by continuously adjusting their behavior in response to […]

Achieving Measurable ROI from Process Control Optimization Projects

Process control optimization is no longer a luxury; it is a strategic imperative. With global competition intensifying and margins shrinking, industrial facilities are discovering that properly tuned control systems can deliver measurable ROI within months rather than years. This blog examines real-world process control optimization ROI case studies and quantifiable benefits from advanced process control […]

Closing the "Lab Lag": Applying Soft Sensors and Inferential Models for Real-Time Quality Control

In the modern control room, we measure almost everything in real-time: flow, temperature, pressure, level. But the one thing that matters most—Product Quality—is often the one thing we cannot see in real-time. Whether it is the Melt Index of a polymer, the RVP of gasoline, or the moisture content in a dryer, operators are often […]

Reducing Steam Consumption & Flaring Through Advanced Process Control (APC)

In the oil, gas, and petrochemical industries, excessive steam consumption and unnecessary flaring are often accepted as the unavoidable "cost of doing business." However, in an era of tightening environmental regulations and fluctuating energy costs, these losses represent a massive opportunity for reducing steam consumption in petrochemical plants and minimizing flaring events in oil and gas operations. From a […]

Grade Transition APC: Synchronized Multivariable Control for Continuous Processes

In the world of continuous processing, whether is it polymers, petrochemicals, or specialty refining, steady-state operation is straightforward. The real challenge, and the real danger to your profit margins, lies in the transition between product grades and time spend during the transition. Moving from Grade A to Grade B, whether shifting viscosity, molecular weight distribution, color […]

The Hidden Culprit: Best Practices for Control Valve Diagnostics in PID Loop Performance

In the hierarchy of process control problems, the control valve is often the "usual suspect" and for good reason. Industry studies consistently show that over 30% of control valves in operation suffer from performance-degrading mechanical issues.[1] Yet, when a PID loop oscillation occurs, the first instinct of many engineers is to "detune" the controller. This is a band-aid, not […]

The Role of Real-Time Monitoring for PID/APC Maintenance: Transforming Reactivity into Proactivity

Industrial facilities lose critical efficiency and profitability every month—often without realizing where the losses occur. Control loops drift subtly out of specification, equipment deteriorates undetected, and operators discover problems only when systems fail. Real-time monitoring of PIDs and Advanced Process Control systems transforms this pattern, shifting maintenance from reactive troubleshooting to systematic performance optimization. The […]

Simulation-Based Training: Bridging the Process Control Skills Gap in Modern Plants

The process control industry faces a critical talent crisis. An aging workforce approaching retirement, increasing competition from tech sectors, and increasingly complex automation systems create a perfect storm: facilities need highly competent operators, yet traditional training methods fail to develop the expertise required. Simulation-based training has become the primary solution for improving process control efficiency […]
