Answer Posted / sohail malik sngpl pakistan
Antisurge control system is basically to protect the for
example boost compressor.
surge may occur in a gas compressor when the suction flow
may decreases and the isontropic head going to rise then
our surge margin reduces and condition goes to compressor
surge.
in anti surge control system an control valve works for
example if suction flow reduces this valve open to allow
discharge pressure into suction resultant the our condtion
goes to safe margin.
in antisurge control system if 25% reduces in suction flow
antisurge system generate 1 pulse and if 5 pulses generate
in 10 seconds the turbine engine or other facility should
be Shutdown.
