OVERVIEW Indirect heating of processes by organic thermal-liquid fluids offers highly reliable operation, and the heat transfer systems are generally treated as low-maintenance utilities. Occasionally, the heat transfer fluid can become contaminated, resulting in the formation of sludge particles, or…
My first distillation dream occurred about 30 years ago, and yet, I recall it as vividly as if it were yesterday. In it, my distillation-column design work started with a vapor-liquid thermodynamic model that was widely regarded as perfect. I…
Feeder combines speed with accuracy Hapman The PosiPortion feeder (photo) offers a 2-in-1 feed screw option that dramatically improves batch accuracy without compromising speed. A two-speed delivery scheme, consisting of a fast turning “bulk-mode” and a slower “dribble-mode”, are used…
The mechanical design and material science of pH-sensor technology have evolved dramatically over the last century. Current-day uses include a wide range of applications from high-purity pharmaceutical processing to wastewater treatment. Some of these applications pose high challenges to pH…
When it comes to managing regulatory documents such as product labels, bills of lading, and certificates of analysis (COA), virtually all manufacturers in the chemical process industries (CPI) face the same challenge — getting the right information into the right…

To unearth the fundamental causes of vibration-related pump troubles, pump end-users and original equipment manufacturers (OEMs) typically have relied on a concise array of vibration field-test parameters. Conventional trial-and-error vibration troubleshooting methods often fail to achieve the longterm, trouble-free pump…
Relief systems are the last line of defense for chemical process facilities. Verifying their capability to safeguard equipment integrity becomes important as process plants age, increase their capacities to adjust to new market requirements, undergo revamps or face new environmental…
