Process engineers understand how to harness the power of closed-loop multi-variable control in their plants. The evolution of digital control in the chemical process industries (CPI) has provided that power. Yet digital control represents just one facet of optimization and…
Today, companies in the chemical process industries (CPI) are faced with increased operating expenses, reductions in the number of qualified workers, strong competition and the need to do more with less. To meet these challenges, many companies are making use…
The continuing growth in the importance of chemical processing, including oil-and-gas processing, increases the need to understand prediction methods for chemical properties and chatacteristics and the impact that these properties have on unit operations, process simulation and design. A variety…
Corrosion is a cannibalistic force that usually attacks chemical process equipment from the inside out. That must be why it is often referred to as a hidden cost, because the economic impact of corrosion is becoming impossible to overlook. As…
Optoacoustic gas detection determines gas content via the measurement of acoustic pressure waves that are propagated as a gas is irradiated under an appropriately tuned light. A gaseous-mixture sample passes through a membrane into a measurement cell, which contains an…
Exactly three years ago, in the July 2005 issue, this page began with a reference to a perfect storm, whereby then-record-high oil prices of $60/bbl and a relief in capital costs were expected to get the chemical process industries (CPI)…
According to experts in flow measurement, any chemical processors seeking to optimize its processes in an effort to offset the rising prices of natural gas, electricity and raw materials may want to look at improving measurement and control…
Plant performance and safety are key issues for the chemical process industries (CPI) and level measurement plays a crucial role in both. Level measurement helps maintain material inventory at economic quantities, improves product quality and ensures a smooth continuous…
Many types of industrial processes utilize liquid level sensors to provide the information needed to monitor and control a process. This enables the design parameters to be maintained in order to produce the end product at the desired level of…
A Low Parts Count Makes this CO 2 Monitor Economical Boasting an in-house design and accurate CO 2 detection between 0 – 10,000 ppm, the ZG106A-M has a uniquely low parts count, making it an economically competitive option for determining…
