Dear All,
We have 3 stage Propylene Refrigeration compressor. Which is operating at 0.3 kg/Cm2g(-41°C) , 2.1 Kg/cm2g (-20°C), 5.8Kg/Cm2g (4°C) at each stage suctions and discharge will be 20.1 Kg/Cm2g (86°C). The Propylene is condensed with Cooling water only.

After taking Propylene in each stage drum,all the drums are at 9.5 kg/cm2g. So, while we are starting this compressor, how much opening should be kept for each stage suction PVs?. (Antisurge we have to open fully).
Note that, This is a fixed speed Motor driven compressor and all the suction PICs and Antis urge FICs are controlled by CCC.
If anyone having experience in starting up refrigeration (Centrifugal) Compressors please help me in reply.
Thank you.
Anjaleyan.
