Hydrocarbon Processing Awards 2020—FINALISTS

This special section details all finalists within each category for the fourth annual HP Awards. The winners will be announced on Oct. 1.

Taking back what’s yours: Extractive desulfurization minimizes octane loss in FCC naphtha hydrotreating

Aggus, B., Massa, M., INVISTA Performance Technologies

Generating octane barrels has always been a tough road for refiners. In 2020, this road got a lot tougher with olefin saturation and octane destruction being collateral damage as refiners strive to achieve the sulfur limit in the gasoline pool.

Advanced analytics drive IIoT success

Zinsli, J., Seeq

Refineries and petrochemical plants face similar challenges in daily operations. Each must mitigate risk, anticipate maintenance, optimize operations and minimize expenses. To achieve these goals, plant personnel rely heavily on data to drive decisions.

Advanced cooling tower water treatment—Part 1

Refineries, petrochemical plants and similar facilities rely on a significant number of heat exchangers for process control and product formulation throughout the plant.

Intensification of sulfur processing units by oxygen enrichment and process flowsheet optimization

Yang, W., Hyundai Oilbank Co. Ltd.; Lewis, J., Racz, A., Advisian, a Worley Company

The consistent global trend toward improvements in air quality and tighter regulations on emissions, as well as the International Maritime Organization’s shipping regulations, continue to mitigate sulfur levels—not only in conventional transport fuels (petrol and diesel), but also in jet fuels, fuel oils and other heavier distillates.

Maximizing diesel hydrotreater profit by multivariable optimization: A case study

A diesel hydrotreater (DHT) is a critical unit within an oil refinery. A DHT processes the diesel range fractions obtained from different units of the refinery—such as from the crude distillation unit and the delayed coker unit—to adhere to diesel fuel market specifications.

Business Trends

Nichols, Lee, Hydrocarbon Processing Staff

Rovuma LNG, a JV comprised of ExxonMobil, Eni and China National Petroleum Corp., will likely delay its final investment decision (FID) on the group’s $30-B Mozambique LNG project.

Doing more with less: Extending critical fluid system resources

Menz, B., Swagelok

Fluid system operators are tasked with maximizing value from their systems to enhance plant and refinery operations.

IMO 2020 and the importance of nonlinear blending properties calculation

Curcio, L. E., Refinery Automation Institute, LLC

With 2020 here, fuel blenders, shipowners, and fuel oil producers and users are concerned about what will happen this year, with the sulfur content in bunker fuel reduced from 3.5 wt% to 0.5 wt%, as per International Maritime Organization 2020 (IMO 2020) rules.

Demineralized water system design: Considerations for the petrochemical industry—Part 1

Fan, J., Ananthanarayan, S., Hodgkinson, A., Advisian, a Worley Company

Site utility leads, engineers and other professionals in the hydrocarbon/chemical processing industries (HPI/CPI) are facing a perfect storm of increasing demineralized water demand, end of life of existing demineralized water plant equipment, changing source water quality, corporate directives to diversify water sources, and pressure from regulators and community stakeholders to minimize the volume of waste generated from water treatment.
