Validation of Antisurge Valve of a Centrifugal Compressor using Dynamic Simulation in Aspen HYSYS

waqasmanzoor · Nov 12, 2014

Dear All,

I have to validate an Antisurge Valve of a centrifugal compressor using Dynamic Simulation in Aspen HYSYS. Does anyone have worked on a similar project?

Also I have to specify initial tuning parameters for the Antisurge controller. Please advise specifically for Aspen HYSYS software.

I am new to these types of calculations. Therefore, I reverted to this forum like I did for many of the other process engineering calculations

Thank you

Dear Waqas,

I have done the simulation for CO2 and synthesis compressor at ammonia/urea plant.

First you have to run the compressor in steady state using compressor curves data reproducing the operating conditions
Once steady state compressor simulation with curves is achieved. Insert the anti-surge valve and provide all the dynamic parameters.

Do note that the tuning parameter you supply to controller in hysys may differ from actual plant parameter. But it will give you an idea.
