Pumps and compressors are the most common equipment for fluid transport in process plants. However, most process engineers understand about pumps and compressors too superficially to perform in-depth calculations and troubleshooting of pump and compressor systems. This course provides essential knowledge on specific requirements for each type of pump & compressor and typical P&ID examples that process engineers should understand. It also covers the basics of shaft sealing, seal flushing systems, series vs. parallel operations, variable speed driver effects, viscosity corrections for centrifugal pumps. It also explains the difference between compressors and blowers (or fans), so that engineers can calculate suction and discharge conditions correctly.
Engineers e.g., chemical engineers and mechanical engineers, process design engineers, process engineers, engineering company engineers, any technical personnel dealing with pumps and compressors in terms of design and engineering, specification, and troubleshooting of pump & compressor systems
