90-05: Estimating Operational Service Time of Heat Exchangers ManualPredicting operational service time of heat exchangers between forced maintenance outages is a subject, which has been studied intensively for many years. Numerous technical and economic advantages would occur if such predictive data were available, to permit appropriate preventive actions to control potential fouling problems developing on either the cooling water side or the process fluid side. The calculation methodology developed by Kern and other

This study examines the total installed cost using these two alternatives

and propane

with emphasis on those areas affecting energy consumption

the motor was removed from service

Examples of fracture failures of a wide variety of components are presented

and surface fouling methods involving coupons

This paper discusses some of these problems and their circumvention

Opportunities exist to utilize existing instrumentation in some cases along with new measurements to synthesize systems that are effective

health and safety concerns

Portable remote monitoring systems have been developed and their use is discussed

Any chance we have to go over mutual problems and add to understanding is sure to be worthwhile
