This brief introduction to nanotechnology provides a basic understanding to those new to the field Most chemical engineers and chemists are aware of the recent excitement generated by nanotechnology, but many may wonder what all the fuss is about. Nanotechnology…
Hans Turck This compact I/O block module handles up to 16 signals This new series of compact I/O modules (photo) uses technology based on the reliable BL67 modular I/O system, and includes different BL67 electronic components and a programmable gateway…
This unit offers measurements for low flows in the milliliter range The SLQ-HC60 (photo) fills a gap in the existing range of products for precise measurement in the low flowrate range, below 100 mL/min. This water-resistant meter operates without moving…
Eye injuries of all types occur at a rate of more than 2,000 per day in the U.S., and half of those occur in the workplace. In 2006, the U.S. Bureau of Labor Statistics (BLS) reported over 52,000 workplace injuries…
There is increasing pressure on industry to reduce both energy usage and the associated CO2 emissions. An important and profitable action that industry can take is to recover more process energy and thus improve the efficient use of that energy.…
The use of gasketed plate-and-frame heat exchangers has gained tremendous acceptance in the chemical process industries (CPI) over the past 20 years due to their high heat-transfer coefficients, compactness and low cost. However, it is important for the engineer who…
