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.

Inspection: Establish an inspection plan for flare burners

Anwer, A., Ruwais

Flares are prominent in hydrocarbon processing operations. From afar, they can be spotted burning with a high or low flame, supported by a tall steel structure

Selecting the right gas analyzer to optimize monitoring of NOx and other emissions

Kamphus, M., Emerson Automation Solutions; Williams, K., Emerson

Combustion processes of all types generate emissions of one kind or another.

Global Project Data

Hydrocarbon Processing’s Construction Boxscore Database is tracking nearly 1,600 projects around the world.

Industry Metrics

Rhodes, Mike, Hydrocarbon Processing Staff

Refinery margins came under added pressure, affected by the downturn in product consumption inflicted by COVID-19 pandemic lockdowns.

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.

Causes of reduced or stopped flow in controlled-volume pumps

Controlled-volume (CV) pumps, also known as metering or dosing pumps, are designed to deliver a small quantity of fluid at a precise rate with relatively high pressure.

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.

Flow modeling as a tool for WHRU performance optimization

Gupta, A., Petro-Chem Development Co. Inc.; Gentry, M. R., Airflow Sciences Corp.

Greenhouse gas (GHG) emissions have become a growing concern for many industrialized countries over the past few years.

Use CFD modeling to improve burner design and operation

Chen, Z., Becht Engineering

Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature.
