Every centrifugal compressor installation utilises an application specific design. While the components within the compressor are tried and tested, the matching of their performance capabilities to the process application is not. This is because for each duty and its particular requirements, an application-specific selection (combination) of compressor stages (impellers) and casings is made.
Whether it is for a new centrifugal compression facility or the revamp of an existing one, the success of this procedure hinges on the integrity of the compression specification. The OEM can do a good job of putting together a machine that matches the performance indicated by the client-produced datasheets. However, matching a compressor to the datasheet is not necessarily the same as matching a compressor to the required duties.
The machinery and the wider system need to be a marriage of what the compression and the wider production facilities are each capable of, across many years of operation. It is not productive to treat the compressor like a black box that must do whatever the production system needs from it, neither is it productive to expect the production installation to just live with what the compression system does. For success, the compression specification needs to complement the greater production facility and vice-versa – ensuring that the two can work effectually in unison.
Mirade therefore believes that a truly effective compression specification is more than just a definition of machinery, but a definition of the optimal way in which the machinery and wider production system will operate together. Anything less can potentially reduce productivity and operability of the entire asset.
A Unified Approach to Compression & System Design
A Solution that is not only Optimal for Compression,
but the Overall System too
This is facilitated by Mirade’s expertise in a systems and holistic approach to the design process as well as an ‘in-house’ capability to derive application-specific centrifugal compressor designs and performance curves – see web pages “compressors in new and young assets” and “simulations”.
In instances where particular process engineering or flow assurance expertise is required, Mirade can bolster the strength of multi-discipline project teams through their associations with other specialist consultancies.
