Understand Compressor Operation as Chemical Process Engineer

Compressors are vital for efficiently transferring gases and significantly increasing their pressure. These essential machines are indispensable across a wide range of industries, prominently featured in the oil and gas industry – from midstream operations to downstream refineries, and within petrochemical plants and various chemical processing applications. Due to their relatively high cost compared to other plant equipment, a thorough understanding of compressor types, their operational principles, common problems, and effective solutions is crucial.

This course delves into the fundamental compressor principles, exploring how they manifest in both centrifugal compressors and reciprocating compressors. We'll highlight the key differences between compressing compressible gases and pumping incompressible liquids.

The course provides a detailed examination of dynamic compressors, covering their various types, followed by an in-depth look at positive displacement compressors, again exploring different configurations. We'll use comparative analysis to clearly outline the advantages and disadvantages of each compressor type, empowering you to make informed decisions.

A core focus will be on understanding the compressor curve and its interaction with the system curve. You'll learn how to plot the compressor curve against the system curve for both dynamic compressors and positive displacement compressors. We’ll analyze how the compressor and the overall process system interact, and how the compressor responds to process changes and disturbances.

Furthermore, we will address compressor surge – its causes, detrimental effects, and proven best practices for prevention. Finally, the course explores various control methods to maintain optimal compressor operating points, applicable to both centrifugal compressors and reciprocating compressors. Master these techniques to ensure efficient and reliable gas compression.
