Lee, S., Kim, E., Jeon, S., SK Energy

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

Nichols, Lee, Hydrocarbon Processing Staff

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.

Upgrading the bottom of the barrel

Elshout, R., Energy Systems Engineering; Bailey, J., Brown, L., Nick, P., Consultant

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

Hoehn, R. K., Bradley, S. A., Mucek, M. W., Honeywell UOP; Anada, H., Osuki, T., Nippon Steel and Sumitomo Metal Corp.

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

Alshaye, A., Saudi Aramco

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

Kumar Dhar, P., Meesala, L., Valavarasu, G., Rao, P. V. C., Sriganesh, G., Hindustan Petroleum Corp. Ltd. (HPCL); Kumar, P., Hindustan Petroleum Green R&D Center, Hindustan Petroleum

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.
