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…
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…
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…
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…
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…
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…
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…
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…
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…
