Process Optimization

Retrospective: Then and now— Looking toward the future

Kennedy, J. P., OSIsoft

In 1982, I wrote an article called “Using process computers as robots for refining operations,” which was published in the May issue of Hydrocarbon Processing.

AI: How AI and machine learning benefit refineries and petrochemical plants

Welsh, T., AX Control

Embedding machines with artificial intelligence (AI) allows them to learn from their past experiences.

Turbomachinery: Increase rotating equipment uptime with laser shaft alignment

Silveira, J. D., Nexxis

The cost of failing to properly align shafts or belts on rotating machinery adds up to more than the need to physically fix damaged machinery.

Fluid Flow: Advanced flow dynamics analysis reduces design time for high-performance processes

For a process facility, guaranteeing maximum profit over its lifecycle while increasing safety and taking care of environmental aspects means continuous improvement toward operational excellence.

Optimization: Improve LP model accuracy

Mohamed, S., Saudi Aramco

Using quadratic equations rather than a linear relationship in a linear programming (LP) model increases the model’s accuracy and reduces money left on the table.

USB threat vector trends and implications for industrial operators

Knapp, E., Honeywell

These are interesting times for universal serial bus (USB) security.

Maximize existing xylene loop profitability

Sakaguchi, T., Idemitsu Kosan Co. Ltd.; Molinier, M., ExxonMobil

Paraxylene (PX) separation is an energy-intensive process, as are most industrial chemical separations.

Improving resource efficiency of industrial processes with TOP-REF methodology—Part 1

Radatz, H., Schembecker, G., TU Dortmund University; Raffray, G., Sellis, D., The CoSMo Company SAS; Boto, F., Echeverria, Z., Fundación Tecnalia Research and Innovation; Carrion, A., Herce, C., Oto, F., Fundación CIRCE—Centro de Investigación de Recursos y Consumos Energéticos; Gil, A., University of Zaragoza; Arias, A., Borrego, R., DOW Chemical Co.; Romero, J., Fertinagro Nutrientes S.L.; Jacinto, J. T., Petróleos de Portugal

The processing industry consumes significant amounts of resources, such as materials and energy, to produce valuable goods for society.

Allocate new plant focus to steam system design—Part 1

Risko, J. R., TLV International Inc.

New plant construction includes expectations for optimized production performance to achieve targeted profitability. After a capital investment decision is made to build a new plant, it can take years to secure critical items, including property, permits, technology licensors, front-end engineering and design (FEED), staffing, training, engineering and procurement for final design and construction.

Octane upgrading technology to boost value of light paraffinic feeds

Aggus, B., Massa, M., INVISTA Performance Technologies

In November 2017, US crude oil production eclipsed the 10-MMbpd mark, setting the highest production record in history.
