Alternatives to flare gas recovery for sour refinery flare gas

Trimeric Corp.: McIntush, K.  |  Mamrosh, D. L.  |  Jones, R. A.  |  Beitler, C. M.

For many sour gas streams present in a flare header, less expensive options than flare gas recovery may exist. The compressors, liquids management, downstream treating and other systems required for flare gas recovery (FGR) can be expensive to install and/or operate reliably. Some refineries allow the flaring of sweet gases.

Vibration studies offer valuable lessons for correcting problematic operations

Suncor Energy Inc.: Tharakan, J.

All plants have a vibration monitoring program for rotating equipment. Portable instruments measure vibration at the bearing housing of machines at horizontal (x), vertical (y) and axial (z) directions. The frequency spectrum helps diagnose the causes of vibration.

Advance analytics to keep pace with production

Thermo Fisher Scientific: Van Cann, B.

Predicting the state of the energy industry a year or two from now is difficult. At best, potential scenarios can be envisioned, as in the International Energy Agency’s (IEA) World Energy Outlook 2016. Through this analysis of data and market reports, the IEA casts its projections for different scenarios to the year 2040. The IEA expects the fastest growth to occur in renewable energy, given recent climate pledges by global governments.

Implement proactive asset management techniques

T.A. Cook Consultants Inc.: Natarelli, J.

The drop in crude oil prices since 2014 has impacted both upstream producers and downstream players. Upstream producers—those responsible for exploration, drilling and production—were the first to feel the effects. While refining margins benefitted from the drop in crude oil pricing, they began to suffer when record surpluses of gasoline and diesel flooded the market a year later.

Expand crude diet flexibility through comprehensive oil management

Baker Hughes: Arensdorf, J.  |  Hoffman, G.

One of the primary means for refiners to boost profitability is to improve crude diet flexibility. Many refiners are challenged with increasing their margins while the quality of the global crude oil supply declines.

Saudi Arabia may raise light crude price to Asia for third straight month in April

(Reuters) -- Top oil exporter Saudi Arabia could raise the price of Arab Light crude it sells to Asia in April for a third straight month after Middle East benchmark Dubai crude strengthened on OPEC cuts, four of seven respondents said in a Reuters survey of refiners and traders on Wednesday.

Enhance reliability of process pumps with lubrication management for antifriction bearings

Indian Oil Corp. Ltd.: Sahoo, T.

Rolling bearings must be adequately lubricated to operate reliably and to prevent direct metal-to-metal contact between rolling elements, raceways, cages and other components. The choice of a suitable lubricant and lubrication method, and controlling contaminants, are important for improving the reliability of the machinery where these bearings are used.

Hybrid technique for electroslag strip cladding of critical process equipment

Lincoln Electric: Chattopadhyay, P.  |  Nateghi, A.

One of the major challenges in the oil and gas processing industry is to strike a balance among handling the changing qualities of petroleum products and byproducts, increasing the productivity and service life of critical components and reducing environmental hazards. As an example, new refineries are moving to applying conversion methods, such as hydrocracking, to increase yields, while also utilizing conventional distillation. This juxtaposition translates into a higher Nelson Index rating. Greater refinery complexity makes processing low-quality crude oil difficult, if not impossible, thereby precluding bottom-of-the-barrel products.

Improve understanding of corrosion inhibitor technology for processing high-acid crudes

Dorf Ketal: Ondyak, J.  |  Noland, J.  |  Shah, P.  |  Subramaniyam, M.

For corrosion risk assessment and control, ample published research exists on the inherent corrosivity of combinations of naphthenic acid and sulfur in refining systems, but not on the chemistry and mechanism of corrosion inhibitors. This work offers refinery engineers insight into the construction of corrosion inhibitor molecules, as well as how differences in molecules impact the performance of the inhibitor and the risk of fouling in crude units and hydroprocessing units.

China’s Sinopec to spend $29 B upgrading four refining bases

BEIJING (Reuters) -- China's Sinopec group, parent of Sinopec Corp, will invest $29.05 billion to upgrade four refining bases between 2016 and 2020 to produce higher-quality fuels, the company said in an emailed statement on Thursday.
