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…
The concept of tray stability can apply to bubble caps and be used as an alternative method to determine the minimum efficient capacity of these devices. A new stability correlation for bubble-cap trays is proposed and checked against FRI data…
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,…
A practical look at the need for validation, as well as conceptual considerations and a case study This article addresses the need for experimental validation of computer-generated distillation column simulations , and discusses the main concepts involved with experimental validation.…
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…
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,…
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…
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…
Viscosity, power consumption, commercial availability and lifecycle cost analysis are all important considerations in pump sizing. An automated spreadsheet method helps engineers take those factors into account in centrifugal pump selection Many aspiring chemical engineers enter industry after university study…
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…
