All chemical process industries (CPI) operations involving combustion need to be concerned with the emission of combustion products, due to their potential environmental and health impacts. This one-page reference provides information about several of the most common combustion byproducts from…
This column is based on “Isopropyl Alcohol Production from RG Propylene – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/isopropyl-alcohol-production-cost. Isopropanol (isopropyl alcohol) is among the most commonly produced lower alcohols — ranked third in…
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,…
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…
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…
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.…
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 it comes to managing complex global supply chains, visibility and collaboration are the name of the game. To drive it, companies are embracing digital strategies The global chemical process industries (CPI) are undergoing a major transformation brought about by…
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…
