This course focuses on exploring the design characteristics, efficiencies, operating behaviors, reliability, and maintenance considerations of centrifugal compressors and steam turbine drivers.

Centrifugal compressors play a vital role in numerous petrochemical and industrial plants. These compressors typically operate at high speeds and are exposed to elevated temperatures. The operation of a compressor is limited by the surge and stonewall conditions. Additionally, the performance of the compressor is influenced by variations in operating conditions.

Gas turbines, operating under highly critical conditions with elevated temperatures and significant centrifugal stresses, require complex monitoring and protection systems. Accurate instrumentation, monitoring techniques, troubleshooting skills, and well-designed maintenance programs are imperative for maximizing the operational availability of these machines.

By gaining a deep understanding of centrifugal compressors, participants will be equipped with the knowledge necessary to ensure smooth and trouble-free operations. This enhanced comprehension will contribute to the efficient and reliable performance of centrifugal compressors.
