Unlocking FCC potential with an innovative catalyst solution

Tavares, T., W. R. Grace

In 2010, a JV embarked on the deployment of a MHY zeolite technologyb developed at the Massachusetts Institute of Technology. This novel zeolite technology improves traditional zeolite catalysts through the introduction of highly interconnected channels of medium pore size, which enhance diffusion of feed molecules inside zeolite crystals, leading to higher-value product yields, improved process efficiency and increased refinery profitability.

Hydrocarbon Processing Awards Winners

Hydrocarbon Processing, the downstream processing sector’s leading technical publication, has announced the winners for its third annual awards. The HP Awards celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.

The future of wireless control

Boger, H., Consultant

In 1864, James C. Maxwell predicted the existence of radiowaves by means of a mathematical model. The so-called Maxwell equations are the most famous and successful formulas. In 1884, John H. Poynting realized that the Poynting vector would play an important role in quantifying electromagnetic energy. In 1888, bolstered by Maxwell’s theory, Heinrich Hertz first succeeded in showing experimental evidence of radiowaves using his spark-gap radio transmitter. The prediction and evidence of radiowaves were the beginning of wireless power transfer (WPT).

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.

The future of digital transformation and smart manufacturing

In today’s challenging oil and gas operations, it is vital to have a robust operating system that supports each facility’s goal of operational excellence (OE). Digital transformation and smart manufacturing are being implemented by Saudi Aramco as a coined umbrella term: integrated manufacturing operations management system (imoms).

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.

A dynamic 1D model for accelerated reactor cooling

Capra, M., Aggreko

Refinery hydrofining units must undergo planned and emergency shutdowns for catalyst changeover.

Opportunity crudes and refinery challenges during hydrocracking operations—Part 2

Refineries worldwide often face practical challenges and operating issues when processing opportunity crude oils to maximize profit margins.
