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.

Can ammonia be a future energy storage solution?

Ammonia is well known as a fertilizer. However, it is also a potential carbon-free fuel and an excellent solution for storage of renewable electricity, especially if the syngas needed for producing the ammonia is made by electrolysis.

Business Trends: The ins and outs of construction contracts

Shahani, G., Berg, J., ShureLine Construction

Industrial construction projects are becoming larger and more complex, with shorter schedules. To meet these challenging requirements, such construction projects are often executed by multiple entities located in different countries that may have different business objectives.

Digital: Better maintenance through better data

Eichelberger, N., Accruent

When I talk to professionals in the refining and petrochemical businesses, they are always interested in how new technologies can improve operational efficiency, make plants safer and increase profitability.

Executive Viewpoint: Succeeding against cyber attacks

No doubt exists that the added connectivity that modern control and automation systems deliver offers a myriad of benefits. By embedding computing within the process and utilizing edge and cloud technologies, it can provide greater visibility. It creates a digital thread for the plant and allows both equipment and the processes to be analyzed, as well as giving prescriptive advice.

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.

How changes to functional safety standards can optimize fire and gas detection

Naranjo, E., Emerson Automation Solutions

ANSI/ISA-84 is one of the most influential standards in functional safety and has been a driver for instrumented process safety improvements over the last 20 yr. It is a comprehensive norm covering a wide range of aspects related to functional safety in process industries, including the entire life cycle of designing, implementing and operating safety systems.

Surviving turbulent times requires deep management changes

Chevriere, J. P., Transmar Consult Inc.; Daily, A., Daily Thermetrics

The Stone Age did not end due to a stone shortage. The Conventional Oil Age was not eclipsed by vanishing traditional oil and gas resources. The Shale Revolution unleashed an era of abundant, new unconventional oil and gas supplies.

Inspection: Best practices for inspecting guyed structures

Anwer, A., Contributing Editor

Guyed structures are common in petrochemicals, oil and gas and chemical industries. Half of the installed flare structures at many facilities are guyed. Various routine inspection programs are in place to examine these structures. This work describes some very basic checks, which should be in place to maintain their mechanical integrity.

Digitalization: Maximize assets with a digital investment framework for oil and gas

Shong, F., Chung, W., Thapar, R., EY Oil and Gas, Ernst & Young LLP

Oil and gas investments are diversifying as the industry leans toward a more digitally conducive environment. Asset analysis was initially evaluated based on an asset’s technical parameters, pricing and operationality. In this new digital world, however, variables such as service quality, innovation, compliance, flexibility and scalability require quantification. Refinery data continues to be critical to evaluate investments, but is often incomplete.
