Effective asset management strives to maximize reliability and performance while minimizing maintenance and operation costs. Asset management improvement is possible by integrating new advances in smart online pump monitoring ...

The liquefied natural gas (LNG) industry continues to grow worldwide, and there are many LNG terminals planned for the US in response to growing natural gas demands. This tutorial covers the LNG supply chain with emphasis ...

Preliminary process design in 1997 for a new grass roots polymer unit in the Gulf Coast raised the possibility of using a single centrifugal pump instead of two reciprocating compressors to feel ethylene into the reactors. ...

The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. ...

Process pumps experience widely different operating times to failure. U.S. refineries achieve pump mean-times-between-failure (MTBFs) ranging from less than three years to in excess of eight years. While the importance of ...

A submerged electric (SE) pump has been designed and analyzed for high flow applications. The challenges when designing a high power density SE pump are torsional and lateral dynamics and hydraulic stability. The case ...

Traditional commercial centrifugal pump designs have specific speeds (Ns) greater than 500 because low values of Ns are usually associated with low efficiency, pulsation, and a drooping head characteristic. In this instance, ...

It should be an objective to predict bearing housing vibrations by means of finite element methods and avoid them in the design phase rather than to go in for corrective actions on the test bed or in the field. Bearing ...

Mechanical seals are used throughout industry to minimize or eliminate leakage in centrifugal pumps, mixers, and other rotating equipment. The ability of a mechanical seal to meet its performance objectives depends upon a ...

Most of the water supply schemes use electrical power in large quantities. As such, optimization is needed for reducing life cycle cost of the entire establishment in terms of capital cost, minimum downtime, and maximum ...
