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..
The division provides reciprocating compression equipment and aftermarket parts and services for oil and gas production, gas processing, gas distribution and independent power industries.
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..
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..
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..
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 ..
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..
Standardization aids gas compressionMidstream companies traditionally build a few compressor stations in a year, with periodic upgrades to implement new instrumentation technology, increase compressio..
Emergency depressurization is one of the most important design provisions for safeguarding facilities in case of an emergency. To overcome limitations of flare system capacity during such a scenario, depressurization can be practiced in a sequential manner. Presented here are the criteria and calculation methods for designing sequential depressurization, along with guidelines for the implementation of recommended designs.
In 2009, an automation journal commissioned an online survey asking industry observers and practitioners to rank technology trends in 2009 and beyond.1 Table 1 summarizes the respondents’ prefere..
