We injected MAPS(modified ammonium polysulphide solution) at Compressor 1st stage discharge(downstream of compressor interstage cooler) and 2nd stage discharge(d/s of after cooler) with process water as a carrier(temp. 50 deg C,ph-7.5-8.0)for reduction in CN related corrosion and H2 blistering.
We have faced MAPS line choking problem frequently, after choking we cannot push MAPS and process water.
If someone has same experience or expertise ,please suggest forward path.
