When a major asphalt manufacturer experienced random bearing wear in its gear pumps, there was justified concern.
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.
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.
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.
A scientific study was undertaken to evaluate the performance, under dry running conditions, of two types of diamond coatings applied to silicon carbide faces of mechanical seals.
With relatively few exceptions, industry guidelines and standards allow an increased understanding of best practices.
SABIC has awarded AESSEAL a 5-year managed reliability contract for their mechanical seals and seal support systems at the Geleen petrochemical complex in the Netherlands.
An aging ethylene plant historically suffered from plant run length limiting compressor fouling that resulted in a loss of polytropic efficiency and intercooler backpressure buildup.
A.W. Chesterton Co., a leading industrial equipment fluid sealing specialist, has expanded its facilities north of Boston with a new state-of-the-art valve emissions testing facility, an expansive industrial training center, and an industrial equipment service location to support regional customers.
