Vibration studies offer valuable lessons for correcting problematic operations
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.
Implement proactive asset management techniques
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.
Enhance reliability of process pumps with lubrication management for antifriction bearings
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.
Driving innovation in the downstream: IRPC returns to New Delhi
Gulf Publishing Company and Hydrocarbon Processing are pleased to announce that IRPC 2017 will be held April 18–20 in New Delhi.
Improve metering pump reliability through maintenance training
While equipment reliability is not a new concept in hydrocarbon processing facilities, it is increasingly becoming the top priority for plant managers. Plant managers realize that operational efficiency is far from being a passing trend, and is closely linked to the quality and reliability of the equipment used.
Reliability: Troubleshoot hot bearings in hot pumps
The reliability engineering unit supervisor (REUS) working at a 400-Mbpd refinery wrote that he was greatly concerned about a bearing temperature excursion. He realized that certain rules of thumb had been handed down to his maintenance employees, and that not all of these conveyed the same numbers and guidance.
ReTPac concept from MAN Diesel & Turbo recaptures market for refinery applications
Tailored specifically to the requirements of refinery operators, the modular and scalable turbomachinery concept combines centrifugal compressor and prime mover to a single-lift unit, serving refinery applications like hydrotreating and hydrocracking.
Codes and Standards: Overcome technical difficulties in field pumps ordered to API 610/ISO 13709
The continued objective of this column series is to increase awareness of code requirements, interpretations and limitations as they stand today, and the options available to engineers for “alternative engineering.”
