Concentrated acid tank problem? Which expert can help solve it?
Thread Content
The bottom flange of the concentrated acid storage tank is corroded. Which unit has dealt with similar problems?
Supplement, the acid in the acid tank has been drained, and I am worried that hydrogen will be produced in it. How to start a fire?
Diameter 17, height 17 meters. Replace with what?
This is an idea, has anyone dealt with similar problems? There is a passivation film and dilute acid attached to the tank wall
Why does it look like the manhole at the bottom is not open? If the sulfuric acid tank has not been flushed, it will look like the upper part of the manhole has not been filled with sulfuric acid and a passivation film has not been formed. ；
Blind plates are installed on all external pipes connected to the sulfuric acid tank. The bottom manhole of the sulfuric acid tank is opened, and the upper manhole is opened. There are no dead corners. Forced ventilation can be replaced. After passing the combustible gas test, there will be no problem in starting a fire.
