Case history: Failure analysis of a syngas compressor
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
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
“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
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
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
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..
Asia: Future challenges and opportunities for refining sector
Securing the right quality of crude oil, increasing refinery competitiveness and adapting to fast-changing inter-regional trade dynamics are some of the area's key challenges.
Consider catalytic dewaxing as a tool to improve diesel cold-flow properties
Diesel engines rely on effective dispersion of fuel to ensure efficient combustion. In cold weather regions, maintaining the fluidity flow of fuels can be difficult. Catalytic dewaxing is a selectiv..
HP Reliability: Expect adversity, but plan for success
Consider that a major oil refinery was planning a substantial modernization project in 2008. Energy efficiency gains and the ability to process a more readily available crude slate were key motivating..
