Base layer enhancement study for crude oil distillation process

Şanli, H. Ç., Er, B., Tüpraş

Base layer control is one of the most important stages of a process control system hierarchy for refinery applications.

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.

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.

Octane enhancement avoiding both high reformer severity and alkylation

Kauders, P., CDE Projects Ltd.

An innovative refinery process arrangementa converts butane-rich, light paraffinic streams—preferably containing a high proportion of isobutane—into butylene by dehydrogenation.

Leveraging modern flow technologies to improve safety in refineries

The refining industry is facing increased pressures, such as crude oil supply changes, changing product distributions and increasing regulations. These pressure points create a highly competitive market where refiners are looking for options that include digitally transforming operations and adapting new technologies to enhance safety and improve uptime, flexibility and efficiency, while securing their competitive position in a dynamic market. Improving personnel and process safety remains a top focus area for refiners.

Equatorial Guinea plans to invest $1 B to build several energy projects, including the construction of two new refineries, each with a capacity of 30,000 bpd–40,000 bpd, as well as oil storage facilities, a methanol-to-gasoline plant and an LNG expansion project.

A new liquid-phase isomerization process for xylene loop debottleneck and energy savings

Mhatre, S., Warke, V., Reliance Industries Ltd.; Choi, A., Molinier, M., Saple, A., ExxonMobil Chemical Co.

In a typical xylene loop, C8 aromatics are fractionated out of a heavy reformate C8+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C8 aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.
