Event Overview
Transient hydraulic studies can provide valuable insight to important operational concerns driven by either new operating conditions on existing equipment or to evaluate possible transient upset events for large capital investments, such as new gas turbines or centrifugal compressors. These operational concerns can include compressor surge, ESDs, maximum pressure/relief pressure, rate of change in supply pressure, maximum temperature, and other imposed operating limits. In this tutorial we discuss the data inputs, modeling approach, control systems and their influence on installed systems. A few case studies will also be presented to demonstrate multiple mitigation strategies and the impact of upset events on compressor and fuel gas systems.
Attendees will receive 2 Professional Development Hours (PDH) upon completion.
Course Objectives
This course will inform and provide a basic understanding of the transient modeling capabilities for centrifugal compressors using Aspen HYSYS Dynamics for what-if scenarios and as-designed checks for highly transient operations, such as ESD, startup and process disturbances. It will introduce the basics of compressor station modeling and examine several case studies of compressor station dynamic analysis.
Who Should Attend
This is for station engineering and design and end-users interested in updating their compressor system’s equipment or operating conditions.
