Hi everybody
There is frequently tube failure problem in chiller since last 06 months. we are using R-22 in tube side and calcium chloride brine in shell side. this chiller was installed in 2006. We are adding chromate as a corrosion inhibitor in brine and maintaining the chromate 400 to 600 ppm.
We have made some changes in brine flow circuit in 2007.
Earlier circuit
process plant- brine pump-chiller-process plant
Changed Circuit
Chiller- brine tank- brine pump - process plant-chiller
Kindly help me to come out from this problem.
Regards,
DNG
