Differential-pressure (DP) level measurements are widely used in chemical and petrochemical facilities, thanks to their reliability and ease of use. Recent advances are making them even more reliable and easy to use Differential pressure (DP) level-measurement technology (Figure 1) is…
Process industry plants install sophisticated air-pollution control systems, but they can be ineffective if the flowmeters on which they rely deliver inaccurate or unreliable data. This one-page reference provides information on measuring the flow of gaseous combustion products in large…
This column is based on “Cyclohexane from Benzene and Hydrogen – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/cyclohexane-production-cost. Cyclohexane is a relatively stable cycloalkane, present in crude oils in concentrations of 0.1–1.0%. This cycloparaffin…
When wearing single-use protective gloves, sweat can create health and safety issues. Presented here is a look at the causes of the problems and possible solutions A great many situations across the chemical process industries (CPI) require quality hand protection,…
The path to commercialization can be long and arduous, which means the engineers and chemists taking the path must have a good deal of patience, dedication and fortitude. To honor the efforts of those chemical engineers and their companies that…
The presence of certain contaminants can wreak havoc on gas dehydration systems and other similar separation processes, but there are design measures that can help to minimize the issues caused by these substances The presence of the aromatic compounds benzene,…
High-shear, high-speed mixing equipment supplies the mechanical energy necessary to reduce the size of solid particles and liquid droplets in emulsions and dispersions. Emulsions are mixtures of two normally immiscible liquids in which tiny particles of one liquid are suspended…
This column is based on “Activated Carbon Production Process – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/activated-carbon-production-cost. Activated carbon, also known as activated charcoal or activated coal, is an inert solid composed mostly of…
A thorough understanding of enclosed combustion technologies will help engineers to select the proper equipment to balance emissions-control performance with efficiency, costs and complexity Selection of an enclosed combustion solution is a complex process that involves various environmental and operational…
A senior engineer reflects on his career and shares his experience and wisdom with the next generation of engineers While all engineering degrees are inherently valuable and flexible when it comes to career options, the engineering sphere has never been…
