END USER’S APPROACH TO CALCULATING COMPRESSOR PERFORMANCE
MetadataShow full item record
Oil and Gas industry end users have generally approached the topic of centrifugal compressor performance estimation with little consideration to the effect of process gas conditions. This is customary since end users depend mostly on OEM methodologies. This tutorial argues that performance curves are dependent on process gas conditions. The tutorial touches on key gas properties and how they are used in compressor performance calculations. An explanation of the effect of process gas conditions is discussed, and how to develop and make use of invariant performance curves and therefore, estimation results are improved. Finally, dimensionless analysis laws are applied using an end user developed performance calculation tool. The tool has been successfully implemented in plant conditions with proven results.
