A Study on Centrifugal Compressor Performance and Developing Compressor Performance Analysis Software

This report basically discusses the research and the work done on the project entitles A
Study on Centrifugal Compressor Performance and Developing Compressor
Performance Analysis Software. The objective of this project is to study centrifugal
compressor behavior and analyze factors that affect the performance of compressor.
Compressors have a limited operational range that operator will take into seriously. If
exceeded will cause damage to the compressor. Moreover, centrifugal compressors are
costly processing equipment and also consume a lot of energy. Thus, it is crucial to
monitor and controlled compressor performance. Polytropic head are plotted to trend
real time performance monitoring for centrifugal compressors as it consider changes in
gas characteristics during compression. By using Microsoft Excel 2008, the author can
automatically get the outputs by inserting all the data into a calculation sheet after put in
required formulas as a function in Excel. From the compressor performance map one
can analyze the behavior of compressor in real time operation. By trending necessary
variables against time, operator can do a planning on troubleshoot and also composition
analysis. All the theory can be validate by analyzing the results. The author also manage
to construct an interface to determine compressibility factor, Z and polytropic head using
Visual Basic Application.
