Hydrotreating

ART adjusts pricing to reflect higher input costs

ART, the joint venture of U.S. specialty chemicals and materials company Grace and Chevron announced global price increases for its hydroprocessing catalysts amid rapidly rising raw materials and energy costs.

Implement advanced level control techniques to improve crude distillation unit stabilizer performance

Mandal, K. K., Nayara Energy Ltd.

The performance of refinery operations depends on the stable operation of the plant.

2022 HP Awards Finalists

Nichols, Lee, Hydrocarbon Processing Staff

Hydrocarbon Processing, the downstream processing sector’s leading technical publication for 100 yr, has announced the finalists for its sixth annual HP Awards, which celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.

History of the HPI: The 2000s: Net-zero, environmental regulations, capacity acceleration and digital transformation

Nichols, Lee, Hydrocarbon Processing Staff

This final installment of the History of the HPI series details major events in the refining and petrochemicals industry over the past 20 yr, including stricter regulations/initiatives to curb carbon emissions, a safer and more environmentally friendly way to produce and handle chemicals, significant capital investments to boost production capacity and digital transformation.

History of the HPI: The 1990s: Clean fuels and emissions mitigation, M&A, GTL and the fieldbus wars

Nichols, Lee, Hydrocarbon Processing Staff

Much like several initiatives passed in the 1970s and 1980s, the 1990s were a decade heavily focused on environmental issues, with many new regulations being enacted to not only mitigate industrial and vehicle emissions but also to advance the production of clean fuels globally.

Hydroprocessing catalyst reload and restart best practices—Part 2

Dyke, S., PetroQuantum; Pongboot, N., Global R&D

Hydroprocessing (hydrotreating and hydrocracking) units are high-pressure, high-temperature units that have multiple reactors, multiple beds per reactor and specialized metallurgy. Catalysts in these units are replaced on a 2 yr–5 yr cycle, depending on feed quality, unit design, catalyst selection, operational constraints and performance.

Fouling in hydrogen recycle gas compressors

Zardynezhad, S., TurboTech Consulting Corp.

Hydrogen recycle gas compressors are one of the most significant rotating equipment in oil refineries, petrochemical plants and upgraders.

New practice of diameter-transformed fluidized bed reactor in the petrochemical industry

Wang, X., Xu, Y., SINOPEC Research Institute of Petroleum Processing (RIPP)

Motor gasoline standards are becoming increasingly stringent—in particular, the olefins content requirement in motor gasoline is getting lower and lower. Among these standards, China standard motor gasoline VI (B) requires that the olefin content should be < 15 vol%.

How hydroprocessing feed filtration system design impacts process reliability and efficiency

Worrell, J., Clements, M., Echeto, S., Filtration Technology Corporation

Oil refining is an exceptionally complex industry, with much of the inherent complexity stemming from wide regional variances in crude quality and composition, plant capabilities and the types of products produced.
