A Novel Method for Evaluating Sideload Compressor Thermodynamic Performance
Abstract
A method has been developed that allows reasonably accurate sectional performance evaluation of sideload compressors based upon only external measurements available from the streams entering and exiting the compressor casing at the respective nozzles. Estimated sectional thermodynamic performance has historically been limited to acceptance testing where temporary temperature measurement instrumentation has been inserted into the flow path between sections. Accurate longer term evaluation and monitoring of compressor performance once installed and operating has not been possible. While overall, multi-section thermodynamic performance may be obtained by the heat balance method as defined in ASME PTC 10, individual section behavior has not been attainable with the existing procedures. The method logic and equation development is presented for a two-section sideload compressor but can be extended to compressors with additional sections (typically three or four) through the application of some additional logic and calculations. A number of example cases derived from data sheet predicted information and a PTC 10 Type 2 test are included to demonstrate the potential accuracy of the proposed method.
