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.

Steam generator in a hydrocracker high-pressure loop—why not?

Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker.

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.

Editorial Comment: The impact and response of an industry during trying times

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.

Alternatives to ladders and platforms for inspection and maintenance of elevated flare tips

Rastogi, A., Fluor Daniel India

Flare systems are used in refineries and chemical plants as a last line of defense for the plant by burning all unwanted gases and liquid during any upset or emergency condition.
