Sim 3302 Centrifugal Compressor Variable Speed model, shows a motor driven compression system compressing hydrocarbon gas. Gas is passed through a suction scrubber before being compressed and cooled then passed to a discharge vessel.
The model is multipage with an overview, then detail pages on the suction scrubber, compressor and discharge vessel. The compressor page includes the fin/fan after cooler and a dynamic display of the compressor head curve.
The compressor has an advanced anti surge system using adaptive gain and safety protection systems.
Composition of the product gas can be monitored all the way through the system.
The suction and discharge vessels both have their levels controlled using gap controllers.
The suction and discharge vessels are also both pressure controlled by varying the flow in and out of the system respectively.
The speed of the compressor is controlled through cascade control from both the suction and discharge pressures of the compressor varying the compressor motor speed.
