Consider robust tank overfill prevention and independent alarm and gauging systems
Elimination of tank overfills is a significant problem for the petroleum industry. Since most tank receiving operations are manual, the operators rely heavily on tank level gauges and alarms for overf..
HP Reliability: Best practices when trim-cutting closed-pump impellers
Experienced reliability professionals will implement least-risk solutions whenever possible. The following example relates to impeller trimming to reduce the diameter of a fixed-speed centrifugal pump..
HP Engineering Case Histories: Case 77: Random deck vibration with beats
When something vibrates, it is usually in a predictable manner. Motors, pumps, compressors, turbines and centrifuges all vibrate when they are out of balance. Vibration analysis can help predict the s..
Update on lubrication systems
Several case histories illustrate the pros and cons for maintaining rotating equipment under various plant conditions.Example 1In late May 2013, a US oil-mist provider in one of the Great Lakes states..
Control moisture in ‘wetted’ rotating equipment
In turbomachinery, water is one of the most deleterious contaminants. Left unchecked, moisture can severely reduce the service life expectancy of oil-wetted rotating and reciprocating components by as..
Improve quality of lubricating fluids via filtration
Micro-sized dust particles, along with water, can ruin the best lubricating fluids. Contamination of lubricating fluids can occur due to the byproducts of combustion, metal wear, oxidation and more. T..
HP Reliability: Was that a failure or ‘just a repair’?
Purists among reliability professionals are sometimes concerned about the accuracy of the measurement of the mean-time-between-failure (MTBF) of an asset. There are many ways to conduct this failure f..
HP Automation Strategies: ISA108 Intelligent Device Management focuses on work processes
Over the last decade, field instrumentation and analytical chemistry device suppliers have made tremendous progress incorporating value-added functionality into intelligent devices. This includes enha..
HP Water Management: Best practices for RO operations
Widespread use of reverse osmosis (RO) technology in industrial applications began in the late 1980s, following the introduction of polyamide materials that had a significantly higher permeate flow an..
