Maintenance & Reliability

Case 3: Shaft galling in a bushing

Consulting Engineer: Sofronas, A.

When troubleshooting, the cause may not be as obvious as it first appears

Control valves for critical applications

Samson AG: Kiesbauer, J.

Know the causes of cavitation and flashing and how to prevent them

HP Reliability: Expander power absorption methods

Hydrocarbon Processing Staff: Bloch, Heinz P.

Turboexpanders frequently used in refrigeration processes develop power, but recovery of this power has often been of secondary importance. A number of power absorption methods are dire..

HAZROP: an approach to combining HAZOP and RCM

P.E., Rohm and Hass Co: Post, R. L.

A single merged activity provides resource savings

HP Reliability: Oil feed rates for reciprocating compressors

Hydrocarbon Processing Staff: Bloch, Heinz P.

In the lubrication of double-acting compressor cylinders, one of the most important factors is the oil feed rate. Likelihood of over-lubrication is greater than that of supplying too li..

Using wireless technology and the Internet for predictive maintenance

Recent developments in sensors and computational power enable more machines to be monitored inexpensively

Case 2: The hidden load in a three-bearing machine

Consulting Engineer: Sofronas, A.

A screening analysis helps in understanding the cause

HP Reliability: Bearing life and contamination

Hydrocarbon Processing Staff: Bloch, Heinz P.

As if we didn't know, lubricant contamination will reduce bearing life. However, a thorough understanding of the contamination / bearing life relationship is essential if improvements a..

Reduce plant startup problems

ST2EP: Bowdoin, K.A.

Use these guidelines to avoid delays and costly mistakes

HP Reliability: Storage protection of positive displacement compressors

Hydrocarbon Processing Staff: Bloch, Heinz P.

Preservation or corrosion inhibiting of inactive process machinery depends on the type of equipment, expected length of inactivity and the time required to restore the equipment to serv..
