Process Optimization

Process engineering, optimization and advanced process control

Kern, A., APC Performance LLC

A recent Hydrocarbon Processing “Industry Perspectives” survey found that process engineering and optimization is the number-one topic that readers want to read about most. Process engineering and optimization rated higher than the next-highest topic (maintenance and reliability) by a factor of 2:1, and higher than every other topic by a factor of at least 4:1. Process control and instrumentation made the top ten list, albeit below process engineering and optimization by a factor of 7:1.

Cybersecurity: Crucial defenses for critical infrastructures

Small, D., NCC Group

A colleague of mine once suggested to a chemical plant operator that it was a good idea to apply patches to Windows-based supervisory control and data acquisition (SCADA) servers as soon as they become available every month—after all, a lot of them fix security vulnerabilities.

Energy savings opportunities in unifining, CCR and benzene removal units

Kahraman, K., TÜPRAŞ

Opportunities are always available to decrease energy consumption in process units.

Accurate prediction of phase equilibrium properties—Part 1

Katyal, A., Independent Researcher/Inventor

Phase equilibrium properties, such as bubble-point, hydrocarbon dewpoint, water dewpoint, phase envelope, two-phase compositions, compressibility factor, hydrate equilibrium properties, etc., for hydrocarbon mixtures have been calculated accurately using the Peng-Robinson cubic equation of state by implementing constant and temperature-dependent binary interaction parameters in the Van der Waals mixing rule.
