Comparison Of Heat Exchanger Cleaning Methods

When a heat exchanger is cleaned the expectation should be that it will now deliver the maximum possible heat duty.  But an evaluation of most post-clean operation will show that the cleaned heat exchanger is delivering only about 85% of what should be the clean heat duty. For critical heat exchangers which impact process performance […]

Banning Hydrofluoric Acid Won’t Eliminate Risk, But It Will Threaten Fuel Supplies

Safety is the top priority for American fuel refineries, in fact it’s the entire point of my job. I travel around the country, and even to other parts of the world, auditing refinery safety systems, specifically those installed in and around units where hydrofluoric acid (HF) is used to produce alkylate—an essential component of the […]

Don’t Ignore Your Heat Exchangers

Rarely do heat exchangers cause catastrophic events in operating plants. For that reason, they tend to get ignored; little or no proactive maintenance is done and improvements are typically not made unless they become a critical problem. But, if you look at which equipment is responsible for the most economic losses over a period of […]

Process Heater Tube Temperature Monitoring Overview, Best Practices, and Examples

Article published in the Inspectioneering Journal July/August 2022 Issue. High-temperature IR Thermography was pioneered several decades ago as a method for understanding tube temperatures inside fired equipment. While the equipment continues to improve, completing accurate analysis of the data remains very challenging.  It is a complex process to accurately measure tube wall temperatures due to […]
