Internal leakage in hot and cold exchangers
Thread Content
I would like to ask everyone: besides affecting the conversion rate, what other impacts does internal leakage in heat exchangers have?
Factors affecting the SO2 concentration at the outlet of the second absorption tower
Leaks in the heat exchanger are usually caused by poor efficiency of the foam trap (demister) in the upstream dry absorber. If the efficiency of this foam trap (demister) continues to decline, corrosion of the downstream equipment and pipelines will worsen, leading not only to internal leaks but also to external leaks in the flue gas pipes and heat exchangers! This in turn affects the driving rate, making repair welding after parking a common practice.
1. The sulfur dioxide level in the sulfuric acid exhaust gases is significantly above the allowed limits, failing to meet the emission standards. 2. The heat exchanger pipes and flue gas pipes are severely corroded.
Corrosion. Product quality. Catalyst poisoning is also possible
It has too many impacts; it’s better to carry out repairs right away, as the situation will get worse over time.
Haha, President Qin, hurry up and find a manufacturer specializing in low-temperature recovery – the problem is caused by foam and mist in the low-temperature recovery tower; it’s either him or someone else.
