Sulfur

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.

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.

Case study: Extend tube life in a waste heat boiler

Lee, S., Kim, E., SK Energy

The sulfur recovery unit (SRU) separates sulfur from sulfur compounds.

Construction

Nigeria LNG (NLNG), a consortium comprised of Nigerian National Petroleum Corp. (NNPC), Shell, Total and Eni, has greenlighted the expansion of the Bonny Island LNG terminal.

Brazilian developments in the biofuels market

Since the 1970s, Brazil has been a world reference in automotive biofuels, especially bioethanol produced from sugarcane. In 1973, the Organization of the Petroleum Exporting Countries (OPEC) forced a sharp rise in oil prices, triggering a massive slowdown in the country’s economic growth, which had been going through what was dubbed the “economic miracle,” with growth at an average of 12% of GDP. This study gives an overview of the biofuel sector in Brazil, along with the main business challenges and opportunities in this area.
