Maintenance & Reliability
HP Reliability: Expander power absorption methods
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
A single merged activity provides resource savings
HP Reliability: Oil feed rates for reciprocating compressors
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
A screening analysis helps in understanding the cause
HP Reliability: Bearing life and contamination
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
Use these guidelines to avoid delays and costly mistakes
HP Reliability: Storage protection of positive displacement compressors
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..
Case 1: The fatigued motor shaft
First in a series of bimonthly case histories. This one reveals why belt tensioning was the real cause of failure
HP Reliability: Become familiar with turboexpander applications
For many years turboexpanders have been used in cryogenic processing plants to provide low-temperature refrigeration. Power recovery has been of secondary importance. Expander efficienc..
