Special Focus: Process Optimization

Maximizing diesel hydrotreater profit by multivariable optimization: A case study

A diesel hydrotreater (DHT) is a critical unit within an oil refinery. A DHT processes the diesel range fractions obtained from different units of the refinery—such as from the crude distillation unit and the delayed coker unit—to adhere to diesel fuel market specifications.

Best practices for aromatics extractive distillation in integrated complexes
Liu, Z., Wang, Y., Zhao, L., Sulzer GTC Technology

Integrated refining/aromatics/olefins complexes are an efficient and effective configuration to maximize crude oil feedstock value and optimize the value of the entire product chain.

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.

Heat Transfer

Steam generator in a hydrocracker high-pressure loop—why not?

Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker.

Piping and instrument diagrams (P&IDs): Part 2—Causes and management of change
Shah B., Process Engineering Consultant

It is difficult to categorize or group the many reasons for routine or late changes to a P&ID. Some causes are listed here.

Process Controls, Instrumentation and Automation

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.

Improve the safety and efficiency of natural gas sweetening units
Thomas, M., Sreekumar, P., Endress+Hauser

After natural gas is extracted from onshore and offshore sites, it must be transported and processed.

Environment and Safety

Fit-for-purpose fireproofing envelopes
Biradar, B., Agarwal, A., Bechtel India Pvt Ltd.

Although widely used, the term “fireproofing” is misleading as almost nothing can be made totally safe from the effects of fire. Fireproofing refers to the systematic process (including materials and the application of materials) that provides a degree of fire resistance for protected support structures.

Water Management

Advanced cooling tower water treatment—Part 1

Refineries, petrochemical plants and similar facilities rely on a significant number of heat exchangers for process control and product formulation throughout the plant.
