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…
These tips, based on experience, can help engineers keep on top of their many tasks It is not uncommon for engineers to be working on multiple projects at the same time. Have you been in a situation where project priorities…
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;…
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…
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…
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…
Alternative designs for pressure relief systems may offer investment cost savings Pressure relief systems for the chemical process industries (CPI) are essential to prevent a process system, or any of its components, from being subjected to pressures that exceed the…
A practical step-by-step guide for reducing future tube failure Forced outage of a direct-fired heater is the worst nightmare for any operator in a petroleum-refining or petrochemical plant. Since fired heaters are not replaceable by spares, forced outage in many…
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…
