| dc.description.abstract | This tutorial discusses the design and function of surge
control systems, or more precisely, surge avoidance systems
on the basis of the behavior of centrifugal compressors when
they interact with compression systems.
Therefore, the control system, as well as the phenomenon
of surge and stall is discussed. The paper emphasizes the
interrelation between the process system and the compressor.
Regarding the compressor, different methods of controlling
the compressor are discussed, together with different operating
regions like stall and choke. The differences between stall and
surge are explained. Additionally, the impact of the process
and how the process dynamics interact with the compressor is
analyzed, categorized, and explained.
Based on the above, process control and in particular,
surge control systems are discussed. Critical features of surge
control systems are explained, and options for different
arrangements are given. | en |
