Concentrate On Critical Thinking

The complexity of the human body makes critical thinking an essential skill for doctors. It’s also important in our work. However, engineers often learn the value of critical thinking the hard way. Dirk Willard, by way of Editor Traci Purdum's spoken word, tells us not to over-concentrate on the zebras... and let the horses run free.

Microplastics, Leadership Shifts and Industry Honors: April's Top Stories

From a $144 million federal push to address microplastics in drinking water to a CEO transition at Dow and Edison Award wins for chemical giants, here's what moved the needle in April 2026.

Operator Training: When the Subtask Is the Whole Task

Throwing operators into full simulator scenarios sounds thorough, but it can mask the one critical subtask they actually need to master. Human factors engineer Dave Strobhar argues that effective operator training starts by identifying which subtasks carry the highest consequences — loss of containment, asset destruction, major downtime — and drilling those specifically before integrating them into broader scenarios. Using real examples of failed steam-system isolations and a misallocated $500,000 simulator budget, Strobhar makes the case for focused, measurable training objectives over checkbox exercises. The goal isn't to simulate everything. It's to ensure operators get the one decision right when it counts.

Water Is Water — And Other Costly Myths

In this episode of Chemical Processing's Distilled podcast, editor-in-chief Traci Purdum speaks with water treatment expert Brad Buecker about the dangers of the "water is water" mindset in industrial settings. Buecker shares real-world examples of costly boiler failures caused by ignoring water chemistry, explains how water's near-universal solvent properties create scaling and corrosion risks and highlights how geography and climate shape treatment needs. He stresses that single water analyses are insufficient — comprehensive, historically collected data is essential for proper system design. The conversation also covers microbiological fouling, Legionella risks and the growing pressure on surface water supplies.

The Alchemist Signs Off

After nearly two decades, Seán Ottewell retires from Chemical Processing, leaving behind a legacy that spans battlefield bones, Neanderthal adhesives and one particularly memorable hedge. In this episode, Editor-in-Chief Traci Purdum highlights some of his best work...including taking a tinkle on his neighbor's landscaping.

Strait of Hormuz Chaos, TSCA Reform and More — March 2026 in Chemical Processing

Supply chain shocks from the Iran conflict, a contested overhaul of chemical safety law, an ethylene oxide rollback and a green chemistry advance — the month's biggest stories summarized by Executive Editor Jonathan Katz.

The Hidden Costs and Risks of Cross-Training Operators

Cross-training process plant operators sounds simple, but execution is often flawed. Human factors engineer Dave Strobhar explains that effective cross-training must be based on job complexity and demonstrated competency — not arbitrary time requirements. Common pitfalls include inconsistent crew procedures that cause negative transfer of training, inadequate alarm management for operators returning to console roles and subjective assessments that fail to verify true proficiency. Decision-making exercises offer a low-cost way to prepare crews for high-stakes, low-frequency events. Looking ahead, Strobhar predicts automation and AI will fundamentally reshape operator roles, demanding more technical knowledge and sharper system-oversight skills from tomorrow's workforce.

CP Notebook: ACD's Eric Byer on Iran, Tariffs, and the Fight Over Rail

In this bonus episode, Executive Editor Jonathan Katz highlights main points from his recent interview for his Chemical Processing Notebook series. 

Eric Byer lives and works in Washington, D.C., where he fights for more than 400 companies that make up the Alliance for Chemical Distribution. As CEO and president of ACD, he backs the interests of chemical distributors by lobbying on issues such as fair trade policy, rail reform, and chemical safety. He has testified before Congress on several of these issues and keeps his members informed on the trends and legislation that affect their bottom line. I recently spoke with Byer as the Iran war was escalating and his members were already feeling the pressure.

 

Solutions Spotlight: Don't Let the Wrong Mag Meter Cost You

Corrosive acids, erosive slurries, viscous polymers, fluids with variable conductivity — these are the kinds of process streams that prove most challenging. Selecting the wrong technology or materials can mean frequent failures, costly downtime or, worse, a safety incident. Electromagnetic flow meters — also known as mag meters — have been a workhorse of the chemical industry for decades. But there's a lot more nuance to applying them well in tough services than most people realize, and some newer developments in the technology haven't gotten nearly the attention they deserve.

To better understand all that mag meters have to offer, Chemical Processing sat down with Tim Lellman, electromagnetic flow product manager at KROHNE. This episode was sponsored by KROHNE

When Experience Becomes a Blind Spot

Workforce Matters columnist Lauren Neal explains what happens when experience stops sharpening judgment and starts dulling curiosity. The comfort and danger of “we’ve seen this before.”
