Reliability: Achieve longer bearing life in rotary asphalt pumps

Bloch, H. P., Hydrocarbon Processing Staff

When a major asphalt manufacturer experienced random bearing wear in its gear pumps, there was justified concern.

Vibration studies offer valuable lessons for correcting problematic operations

Tharakan, J., Suncor Energy Products

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.

Implement proactive asset management techniques

Natarelli, J., T.A. Cook Consultants Inc.

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.

Enhance reliability of process pumps with lubrication management for antifriction bearings

Sahoo, T., Indian Oil Corp. Ltd.

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.

Driving innovation in the downstream: IRPC returns to New Delhi

Adrienne Blume, Hydrocarbon Processing

Gulf Publishing Company and Hydrocarbon Processing are pleased to announce that IRPC 2017 will be held April 18–20 in New Delhi.

Buyer beware: Are diamond-coated seal faces the solution to dry running?

Seymour, M., Engineering & Quality Systems

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.

Reliability: Monitor equipment condition by collecting vibration signatures

Bloch, H. P., Hydrocarbon Processing Staff

With relatively few exceptions, industry guidelines and standards allow an increased understanding of best practices.

AESSEAL obtains 5-year service agreement with SABIC Geleen in the Netherlands

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.

Extend ethylene plant run length with compressor chemical treatment

Hancock, J. M., Rodrigues, S., Nalco Champion

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 expands Massachusetts training, services hub

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.
