Anti Surge is a process witnessed only in Centrifugal
compressors as Kinetic Energy of the fluid is converted
into the Pressure energy.
Surging is not witnessed in Reciprocating Compressors, as
they are positive displacement Equipments where the
pressure increased is by volume reduction, hence providing
anti surge in reciprocating is not envisaged and not proper.
Anti Surge is witnessed when the flow to the Centrifugal
Compressor is reduced or the density of the fluid entering
the Compressor is altered to greater extent, pressure is
reduced to a lower extent. the surge valve opens and
increases the flow to the suction there by bringing back
the condition to normal operation there by saving the
equipment from damage.
Spill back on the other hand is one way of controlling the
exit flow to the downstream section from the compressor.
One should not confuse with surge control valve and spill
back controller

Answer / ramana reddy
The operation of a compressor at flows lower or output
pressure more than that at a "surge line" causes unstable
compressor operation. "Surging" occurs
