Heat
Exchanger Troubleshooting
In many
cases, heat exchangers do not perform as expected and this can have a
severe impact on plant operation. Cal
Gavin ESD provides a comprehensive troubleshooting service for all types
of heat exchanger, based on 20 years of experience in the field of
process heat transfer.
The
troubleshooting process involves several phases of activity, and Cal
Gavin ESD is unique in offering all of the following:
Site
Investigations
Successful troubleshooting depends upon both the quantity and quality of
the information upon which the investigation is based.
Cal Gavin ESD will attend the operating site in order to gather
and verify the appropriate information.
In addition to the collection of process data (temperatures,
pressure etc.), more sophisticated techniques such as thermal imaging
and radioisotope scanning can be applied.
Heat
Exchanger Modelling
Through its membership of both HTFS and HTRI, Cal Gavin ESD has access
to state-of-the-art heat exchanger modelling codes.
Of equal importance to a successful outcome, the company’s
engineers have many years of experience of the application of this
software. Where appropriate, CFD modelling techniques
can also
be used to provide more detailed information.
Fault
Diagnosis
By combining site data with high-integrity modelling, the true nature of
the heat exchangers operation will be revealed. This understanding
allows the development of rectification proposals.
Corrective Action
Once the true nature of the heat exchanger operation has been
discovered, the way is clear to develop proposals for corrective action.
In many cases operational changes will be sufficient to restore
proper operation. In
addition Cal Gavin ESD can draw from a wide range of hardware options to
engineer cost-effective revamp opportunities.
Closing the
Loop
Following any corrective action, success can (and should) be verified
through post-modification data collection and analysis.
