The global hydrocarbon processing industry continues to expand and modernize to efficiently meet growing demand for energy, transportation fuels and petrochemicals.

Environment and Safety

Utilize distal flame architecture to decrease NOx emissions in combustion systems
Colannino, J., ClearSign Combustion Corp.

In part, the combustion of hydrocarbon fuels is responsible for significant gains in both the quantity and quality of life, and we burn these fuels more cleanly now than at any time in history.

Heat Exchange

Mitigate vibration issues in shell-and-tube heat exchangers
Dole, R., Sridhar, S., Vivekanand, S., L&T-Chiyoda Ltd.

Heat exchanger tubes tend to vibrate when influenced by crossflow velocities.

Process Control/Instrumentation

Optimize alkylation unit operation by using response surface methods
Bird, J., Seillier, D., Teders, M., Jacobson, G., Valero Energy Corp.

A new methodology can be used to optimize the operations of an alkylation unit based on response surface methods.

Process Engineering and Optimization

Use model predictive control to achieve real-time management of a DWC
Blevins, T., Emerson Process Management; Downs, J., Eastman Chemical Company; Donahue, M., Roach, B., University of Texas

A dividing-wall column (DWC) can provide significant savings in energy and capital cost compared to a conventional distillation column design.

Rotating Equipment

Compare pitot tube pumps with high-speed centrifugal pumps for low-flow applications
Khazrai, F., Eskandarlu, A., Chagalesh Consulting Engineers

When seeking a pump for a low-flow, high-head application, there is a temptation to choose a high-speed (HS) integral gear-driven centrifugal pump because of its advantages over multi-stage centrifugal and other types of pumps.

Turbomachinery

Advances in dry gas seal technology for compressors
Bloch, Heinz P., Hydrocarbon Processing Staff; Carmody, C., AESSEAL plc

Compressor owner-operators now have unprecedented and solidly verifiable options.

Water Management

Improve performance and reduce costs of wastewater treatment plants
Putra, Z. A., TMC Chemical BV

The increasing costs of a wastewater treatment plant (WWTP) motivated a major specialty chemical plant to improve the performance of its treatment unit.
