Field performance testing of centrifugal and reciprocating compressors can be a valuable opportunity to assess the base line of the unit once it is operatedfor commercial production. This is true for both new and revamped units, and can help the management team in making production plans according to the real capabilities of the machine.
Many end-users face a gap between expected design performances and “as-tested” ones. If new compressors are shop-tested before they are shipped to site, why should the performance test be repeated in site?
The main reasons to conduct a field performance test are:
determine the actual performance characteristics of the unit when it is installed in the pipeline and operated with the actual process gas.
verify the behaviour of the compressor once it is coupled with other components, such as coolers and scrubbers and the pipeline itself.
verify if the compressor meets the specifications of the applicable purchase contract, therefore if liquidated damages or “make good” actions are required.
