HEAT EXCHANGER CORROSION ISSUE

HEAT EXCHANGER CORROSION ISSUE

(OP)
Dear friends,

For one of S&T heat exchanger (AET type) found leak due to Sour water corrosion. The sour water contains Sulfides, Ammonia and caustic which are creating corrosive environment. However the material of construction of the existing condenser cooler is carbon steel so please advise me 304 SS material is more suitable for this application?

Design temp: 81 Deg C shell side and 76 tube side
Design pressure: 8.6 barg/FV for shell side and 10 BARG /FV for tube side.
service ; SOUR WATER for shell side and COOLING WATER at tube side

Thank you,

regards,
Sameer

Ho long did the original heat exchanger last in service?
