Pumps, Flow and the Fight Against Wasted Energy

This episode digs into three plant-floor challenges that look simple until physics intervenes—bulk solids handling, heat pump-driven distillation savings and a water pump's mysterious cycling problem traced back to Bernoulli's principle.

Trevor Kletz Warned Us

Decades before the Strait of Hormuz closed and refineries started burning, process safety's great philosopher mapped exactly how pressure corrupts risk decisions.

Distilled News: Dow-X-energy Nuclear Milestone, Fatal West Virginia Chemical Release and More

You've Told Your Team to Speak Up. But Are You Actually Listening?

In every organization, informal hierarchies determine who gets heard, who gets interrupted and whose concerns get taken seriously. In process safety, the cost of getting it wrong is high. In this In Case You Missed It episode, Editor Traci Purdum reads a column from Lauren Neal, Chemical Processing's Workforce Matters expert. You can read the column here.

Perceptual Invariants: The Hidden Key to Operator Expertise

Experienced operators don't just know what to do — they know what to watch, regardless of how conditions change. That ability hinges on perceptual invariants: the critical relationships and variables that remain meaningful even as everything else shifts. Human factors engineer Dave Strobhar explains how identifying and reinforcing these invariants is the key to effective operator training. Rather than relying on years of trial and error, structured training programs — including targeted simulator use — can accelerate expertise dramatically. The goal is moving operators from simple stimulus-response behavior to true skill-based thinking that transfers across novel situations, closing the experience gap faster than ever before.

What Do Chemical Engineers Do, Anyway?

If you're a regular listener, you already know the deal — you work in this industry. You've spent your career in control rooms, on plant floors, in engineering offices, running calculations and managing processes that most of the world never thinks about. You know what a distillation column is.

But this episode is meant to be shared with a spouse, a parent, a kid, a friend — someone who's asked you "so what exactly do you do all day?" and you've struggled to explain it.

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.
