  Solution Spotlight: Get Your Coriolis Tube Design Right — or Pay for It Later 14.08.2026 24min

  Selecting the right Coriolis flow meter tube design goes beyond pressure, temperature and flow rate specs — it can reduce how much a plant spends on pumps and energy for the life of a pipeline. In this Solution Spotlight episode of Chemical Processing Distilled, Al Dhanji, chemical industry manager for the Americas at KROHNE, breaks down straight tube versus bent tube designs and how each handles high-viscosity products, slurries and aggressive chemicals. Using honey and water as examples, Dhanji explains why forcing fluid to change direction creates pressure drop, driving up pump size and energy costs. He also covers how tube design affects performance under entrained gas conditions.

  EPA, HHS Move Microplastics from Fringe Concern to Federal Priority 24.07.2026 5min

  In this episode Traci Purdum discusses Lynn Bergeson’s latest article "EPA, HHS Move Microplastics from Fringe Concern to Federal Priority" July 15, 2026 For a long time, microplastics were treated as a recycling problem or a marine litter problem. That changed this spring. On April 6, 2026, two federal agencies moved on the same day in ways that push microplastics squarely into the compliance conversation. Compliance Advisor columns.

  Why Sodium Softeners Make or Break Boiler Water Chemistry 17.07.2026 47min

  In this episode of Chemical Processing's Distilled podcast, host Traci Purdum talks with Brad Buecker, senior technical consultant at Samco Technologies, about sodium softening — the workhorse treatment for industrial boiler makeup water. Buecker explains how hardness ions cause scale, why residual bicarbonate drives corrosive condensate return lines, and how to spot early warning signs of a poorly monitored softener. He shares real-world cases where bypassing softeners or delaying maintenance led to rapid boiler tube failures and six-figure losses, walks through the regeneration cycle and its common pitfalls, and compares sodium softening with reverse osmosis for higher-pressure systems.

  Perceptual Invariants: The Hidden Key to Operator Expertise 15.05.2026 21min

  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? 08.05.2026 8min

  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.

  Concentrate On Critical Thinking 01.05.2026 6min

  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.

  Operator Training: When the Subtask Is the Whole Task 17.04.2026 21min

  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 10.04.2026 38min

  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.
