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.

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.

Industry Perspectives: The Main Column—Hydrocarbon Processing's new podcast series

Nichols, Lee, Hydrocarbon Processing Staff

In December 2019, Hydrocarbon Processing's launched its new podcast series: The Main Column. The podcast series will feature the latest in hydrocarbon processing industry (HPI) trends, technology developments, engineering and operations.

Optimal gas analysis decisions improve ethylene plant operation

Kamphus, M., McMillen, D., Emerson Automation Solutions

One of the most common and important building blocks in the petrochemical industry is ethylene, constituting a huge and fast-growing worldwide industry. Ethylene is an intermediate chemical used to manufacture many commercial products—approximately 200 MMt will be produced in 2020.

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.

HP Top Project Awards

The editors of Hydrocarbon Processing have identified nine projects that are anticipated to significantly impact the global or regional downstream industries. The winners and nominees of the HP Top Project awards will have a considerable impact on the HPI, whether through CAPEX, satisfying domestic or regional demand, diversifying product offerings, or adding to the resurgence in refining and/or petrochemical processing capacity.

Use submerged combustion systems to efficiently destroy hazardous plant waste

Predatsch, E., Armstrong, P., Selas-Linde North America

In the production of clean fuels, plastics and other hydrocarbon-based products, refineries and petrochemical facilities generate unwanted (waste) byproducts. Having no market value, the undesired byproducts must be recycled, minimized or eliminated. Depending on the feedstocks, end products and reactant materials, the unwanted materials can be gases, liquids or multiphase materials.

FCC catalyst deactivation studies to mimic refinery conditions for high-propylene applications

The fluid catalytic cracking unit (FCCU) is a conversion unit located at the heart of many refineries. Its main purpose is to crack crude oil-derived feedstocks into valuable liquid products, primarily LPGs (propylene and butylenes), and gasoline and light-cycle oil (LCO) precursors. The process uses a fluidizable catalyst, comprising an alumina-silica framework and tailored for each refinery to meet its specific needs. Often, the changing of a catalyst includes catalyst testing evaluations, employed by about 50% of the FCCUs in the world. The testing process is cumbersome, in which multiple methods are available to refineries.

Hydrocarbon Processing Awards Winners

Hydrocarbon Processing, the downstream processing sector’s leading technical publication, has announced the winners for its third annual awards. The HP Awards celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.
