I am continuously surprised that in the year 2025, when we can simulate molecular interactions with quantum precision, most process simulation for the oil, gas, and chemicals industry continues to be founded on a cubic equation written in 1976: the Peng–Robinson Equation of State (PR EoS). I recently read a review…

Cavitation is usually blamed on low-flow operation. That’s partly true, at low flow, fluid recirculates near the impeller eye, pressure fluctuates, and vapor pockets appear. But cavitation also develops at the opposite end of the curve — when the pump operates at high flow, near or beyond its design limit. At the f…

Most engineers trust the rule: NPSHa > NPSHr means “safe.” That assumption fails fast when your liquid carries dissolved gases. I learned this firsthand while investigating an unstabilized condensate pump that began to vibrate and lose suction after months of stable service. On paper, everything looked fine: sucti…

I often get asked: “Is it really necessary to correct the fuel flow?” Here’s the truth — it depends on what you’re controlling. If your goal is to maintain heat duty or outlet temperature in a fired heater, then yes, flow compensation is not optional. Why? Because your flow transmitter doesn’t measure energy — it…

In process control, some techniques survive more out of habit than merit. Split-ranging is one of them. It’s the idea of using one controller output to operate two valves across different portions of the range — one takes over when the other reaches its limit. On paper, it seems efficient. In practice, it often intr…
