Material for high-temperature dilute nitric acid reactors
Thread Content
This post was last edited by losren on 2022-7-11 at 21:59. Recently, I was assigned a project that involves using a mixture of dilute nitric acid and sodium nitrate along with mineral powder, with stirring involved. The initial concentration of nitric acid is around 1.5%, and the pH value approaches 7 at the end of the reaction. The operating temperature of the reactor is 220 degrees Celsius; the heating medium is heat transfer oil at a temperature of 260–280 degrees Celsius. The volume of the reactor is approximately 6000 liters. I’m not sure if the right material should be used? Everyone, please give some suggestions. Also, could you recommend some manufacturers that can produce nitric acid-resistant reactors?
For this material, this temperature, and this pH value, manufacturers usually just ignore them!
