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 ambient heat transfer for storage tanks
Heat gain from ambient or heat loss to atmosphere is discussed in standards and technical publications.1, 2 However, the work on fluid/ambient thermal interactions rarely includes an important factor&..
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..
Wide design margins do not improve engineering
Engineers use design and safety factors in sizing and specifying instrumentation or major process equipment, such as pumps, valves and compressors. Design factors are applied to cover the uncertainty ..
HCN distribution in sour water systems
Hydrogen cyanide (HCN) is commonly present in refinery gases. Because of its low volatility and, to some extent, its acidity, it travels through amine and sour water systems in an unusual and, heretof..
