Cleaning of the economizer
Thread Content
Dear seniors, our company is a sulfur-based sulfuric acid producer. The heat exchange efficiency of the economizer in the absorption tower is poor; it is believed that catalyst powder and acid sludge have clogged the fins, resulting in inadequate heat exchange. What are some effective methods to clean the economizer to address this issue? Thank you.
You can try using compressed air pipes; water can easily cause corrosion
Hehe, President Qin – since it’s already a listed company and there’s no shortage of money, we can buy another one as a backup, install a few valves so that one can be used while the other is on standby, thus avoiding the need to clean it when there’s no time for that.
Have you opened it to take a look? Domestic catalysts disintegrate more severely (once, when a leak occurred in a province and it was opened up, the degree of disintegration was quite serious)
There are professional cleaning companies dedicated to this type of cleaning. Monitor corrosion during the cleaning process by using test pieces
