Hydrotreating
Technical considerations for the Heydar Aliyev refinery revamp
The following case study describes the early development phases of SOCAR’s ongoing major revamp project at the Heydar Aliyev Refinery (HAR) in Baku, Azerbaijan, and its interface with the associated Azerikimya (AZK) steam cracking complex near Sumgait. References are made to the related SOCAR polymer project in Sumgayit, as well.
Impact of opportunity crudes on refinery desalter and wastewater treatment performance—Part 1
Refiners are becoming increasingly dependent on opportunity crudes to stay competitive and enhance margins in the industry’s present uncertain state.
Show Preview: IRPC Europe returns to Italy this June
Gulf Energy Information and Hydrocarbon Processing are pleased to provide a preview of IRPC Europe 2018, which will be held June 5–7 in Milan.
Three topics for operational excellence related to a Cr-Mo hydrotreating reactor
Many end users are trying to use feedstock with higher sulfur content for their refineries to increase profitability, but numerous unknown or plausible bottlenecks exist.
Industry Perspectives: Secondary unit construction surges in the near term
Although the refining industry is expected to add more than 7 MMbpd of new distillation capacity by the early 2020s, the global refining industry will witness a boost in secondary processing capacity, as well.
Editorial Comment: The future of refining—sulfur need not apply
According to multiple industry reports, crude oil consumption will continue to increase over the short term.
Upgrading the bottom of the barrel
In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.
Metallurgy solution to prevent polythionic acid stress corrosion cracking in hydroprocessing
Hydrotreating is a staple process found in nearly every refinery. The process removes undesirable feed contaminants, such as sulfur, nitrogen and metals, and saturates olefins and/or aromatics to produce high-quality products.
Consider pitot tube pumps for low-flow, high-head applications
Low-flow, high-head pumping requirements in refining and petrochemical plants make up less than 2% of the total pump population. This minor percentage is creating significant reliability concerns, which result in low mean-time between failures (MTBF), as well as high maintenance costs.
Production of renewable fuels in existing refinery assets: A cost-effective coprocessing strategy
Vegetable oils are a renewable biomass resource used in the production of biofuels. Biodiesel production from transesterification of vegetable oils (fatty acid methyl ester, or FAME) is the primary route for producing biofuels from vegetable oils.
