Considering that a large fraction of the synthesis gas (syngas) produced today is made by steam reforming of natural gas, it might seem curious that in some parts of the world, syngas is being converted into substitute natural gas (SNG).…
In any given chemical processing facility, there may be literally hundreds of operational environments that require protection from excessive pressure. Both rupture disks and pressure relief valves, or the two used in combination, help protect against damage to equipment and…
Get improved precision in batching and filling applications 3i’s Technologies This company’s Rotary Scalpel technology (photo) can deliver small increments of a wide variety of solid materials with precisions of ±0.5 g. The technology consists of a large inlet area…
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…
