Compressor selection

Compressor Selection To select the most satisfactoiy compression equipment, engineers must consider a wide variety of types, each of which offers peculiar advantages for particular applications. Among the major factors to be considered are flow rate, head or pressure, temperature hmitations, method of seahng, method of lubrication, power consumption, serviceability, and cost.

The process application can have a significant impact on the reliability of a compressor. The reliability aspects take on two paths the nature of the gas being compressed and the correct compressor selection for the service. 

The proper compressor selection for the application is probably the most important single factor to achieving long-term reliable operation. For all the factors that make the centrifugal one of the most reliable compressors, a misapplication will negate these most dramatically. 

The type of compressor selected sets the quality of design. The API-based compressor is generally regarded as a higher quality than a catalog blower. Most of the chapter to this point has attempted to emphasize the many factors involved in design. Quality of conformance is a measure of how well the compressor met the specification. One of these measures is the achievement of the desired run time. Another measure is the inspection for conformance of the parts to the drawings.
