New TransCanada pipeline to carry crudes from Alberta to East Canada

TransCanada plans to seek regulatory approval for the project from Canada's National Energy Board by the end of the year, and, if it succeeds, to start construction in 2016. Service to refineries in Montreal and Quebec City would begin the following year and then to Saint John in 2018.

Environmentalists warn of hazards in extracting gas from methane hydrate

The trillions of cubic feet of methane hydrates contained in the ocean's floor are in geologically unstable areas. The fear: One wrong move and an undersea landslide could send massive amounts of a particularly potent greenhouse gas to the ocean's surface and into the atmosphere.

Optimize your compressor maintenance program

Consultant: Geitner, F. K.

One deviation alone might not be enough to bring on a compressor failure, but, when several more deviations combine, the failure risk is known to increase exponentially.

Case history: Failure analysis of a syngas compressor

SABIC Technology Centre: van Zyl, G.  |  Al-Zahrani, E.  |  Al-Meshari, A.  |  Al-Haroon, M.

A first-stage impeller in a synthetic gas compressor failed after 20 years of service. The compressor is a six-stage centrifugal compressor driven by a steam turbine. This case history discusses the i..

Improve pressure drop calculations for saturated water lines

When saturated water flows through pipes and components, it flashes—thus increasing its specific volume and limiting the fluid flowrate. Due to these conditions, the calculation and design for pi..

HP Reliability: Four-stage, low-flow process centrifugal compressor can fill important industry gaps

Hydrocarbon Processing Staff: Bloch, Heinz P.

In the 1970s and 1980s, multistage centrifugal compressors in the 3,000 acfm (about 5,000m3/hr) and lower flow ranges were largely confined to instrument and plant air duties. Three stages with interc..

HP Integration Strategies: Consider procedural automation at a commercial-scale pilot plant

ARC Advisory Group: Miller, Paul

“All processes are batch processes to some degree. Even in ‘continuous’ process plants, processing units will need to be shut down at some point and then restarted to resume production...

HP Boxscore Construction Analysis: Outlook for major revamp projects—Part 2

Hydrocarbon Processing Staff: Nichols, Lee

Worldwide, refiners are investing billions in upgrading and modernizing projects. These efforts are focused on:Increasing flexibility to process heavier, sourer crudesImproving energy efficiencyMeetin..

HP Engineering Case Histories: Case 74: How to determine impact forces when troubleshooting

Consulting Engineer: Sofronas, A.

When troubleshooting failures, it is not unusual for the metallurgical report to indicate that the failure was the result of an impact type of force. The investigator who receives this information mus..

HP Industry Perspectives: US oil and gas executives energized for the year ahead

Hydrocarbon Processing Staff: Romanow, Stephany

A recent survey of US executives by the KPMG Global Energy Institute supports growing optimism in the domestic energy and manufacturing industries. Much of the renewed enthusiasm is strongly linked to..
