|Application||Quench Water Cooler|
|Fouling Issue / Frequency||
In the conventional heat exchanger, fouling reduced the heat transfer (k-value) from 100 to 25% in 4 to 6 weeks.
|Solution / Approach||
A test with the self-cleaning heat exchanger technology was done to prove the performance. After this test, 4 self-cleaning heat exchangers applying recirculation with fluid velocity of 0.45 m/s and a heat transfer surface of 1,250 m2 each were installed. A large storage vessel maintains a constant liquid flow into the self-cleaning heat exchangers. After 3 years of operation, the plant went bankrupt and stopped the production of acetylene
