What problems can occur when washing an empty tower with concentrated acid?
Thread Content
A project is currently in progress that requires washing with 50% H2SO4; I’m not sure what problems this might cause
50% H2SO4 has no oxidizing properties but does have reducing properties; it is also highly corrosive, so it is essential to ensure proper corrosion protection for the materials used.
The question is a bit too broad. Could you be more specific? Is it for designing furnace gas washing?
From a technical perspective, during washing and absorption, the higher the sulfuric acid concentration, the more likely acid mist and acid foam will be generated； At the same time, the higher the temperature of the sulfuric acid used for spraying, the more acid mist and acid foam are generated. This is the primary issue to be resolved. Other issues, such as the removal of harmful impurities like arsenic and fluoride, as well as the high temperature of the sulfuric acid used in spraying, mean that the performance will not be as good as it is when the temperature is lower. There is another issue that isn’t related to the processing aspects: 50% sulfuric acid is, in theory, considered a dilute acid (acid with a concentration of over 75% is classified as concentrated sulfuric acid). So what is the use of such a sulfuric acid with an intermediate concentration?
The acid temperature also needs to be considered in order to determine the appropriate material for the empty tower; the choice of material is what’s really crucial!
It is capable of recovering arsenic; it is the only wet-process arsenic recovery project in the country.
No, I’ve already told you – Zijin Mining uses dry processing methods, while the project we are working on employs wet processing methods. It’s very meaningful; if it’s completed, it will represent a major advancement. I can’t tell everyone yet – I’ll let you know once it’s done.
What is it to be washed? Since nothing can be said, then what is there to discuss? Silence.
