An overview of the many factors to be considered when selecting materials of construction Selecting a material of construction for process equipment in the chemical process industries (CPI) is normally not difficult. The material selection is often based on past…
Accurate measurements of exposures to aerosols and dusts by plant personnel can be tricky. Here is some help for determining exposures and addressing uncertainties Uncontrolled aerosols (defined as suspensions of fine solid or liquid particles in gaseous media) in the…
Process temperature measurement is a constantly evolving field, and new technologies have allowed for more reliable measurements to be realized in many applications Process temperature is the most widely used measurement in the chemical process industries (CPI), and is crucial…
RTD sensors will never exhibit behavior based on theoretical ideals, but understanding the fundamentals behind transmitter-sensor matching will enhance their accuracy Temperature is the most common measurement in the chemical process industries (CPI). It is employed for a wide variety…
Liquid-liquid extraction is a common mass-transfer operation in which a target solute material is transferred from a feed phase into a solvent. The process is used in a number of applications, including: the removal of valuable products from fermentation broth;…
Methionine is an essential amino acid that is not produced by animals. Methionine must be obtained from dietary sources, and its major use is as an animal nutritional-feed additive. Methionine is mainly derived from petrochemical sources. However, biochemical routes to…
The seven commonly made mistakes discussed here often lead to poor filtration and separation performance and many associated problems For almost any chemical process industries (CPI) plant, contamination is a reality that can cause numerous associated — and often chronic…
Adding flare-gas recovery units at strategic locations of an olefin plant can not only reduce emissions, but will save money as well Although gas flaring is necessary at some chemical process industries (CPI) plants or facilities, more and more efforts…
Seven methodologies are described to help operations staff take greater ownership of asset performance The definition of ownership — to act as an owner — implies certain responsibilities. Consider the range of behaviors demonstrated by individuals when it comes to…
Catalysis is among the most important chemical phenomena in industrial chemistry, as well as in many biological and research fields. This one-page reference provides a review of several of the fundamental concepts underlying catalysis. Catalyst basics A catalyst interacts with…
