Fan material selection
Thread Content
I would like to ask everyone: in the neutralization reactor for waste sulfuric acid, which makes up 80% of the mixture in acetylene, along with calcium carbide, as well as the fans and water scrubbers that follow, there should be no sulfuric acid present. When selecting materials, was corrosion caused by the evaporation of concentrated acid taken into consideration? Is it a problem to use 304 austenitic stainless steel? Thank you
It needs to be taken into consideration. If not taken into account, any volatilization of sulfuric acid will cause corrosion. Isn’t stainless steel what sulfuric acid loves the most? Ha, or you could buy a corrosion-resistant one.
Thank you for the answer. The reaction between acetylene and sulfuric acid occurs at a relatively high temperature, above 80°C; I think 304 steel might get corroded in such conditions
Choose corrosion-resistant fans with non-metallic blades, such as fiberglass blades
Thank you, but the owner believes there are too many calcium carbide particles here; non-metallic materials are not durable enough, so austenitic stainless steel should be used instead
