Effect of nitric acid load
Thread Content
I would like to ask the experts: What are the effects on the system of operating a 150,000-ton double-pressure nitric acid plant at a load of less than 70% on a long-term basis? Try to have as detailed data or evidence as possible. Thank you
If it operates at the lower limit of its design parameters for an extended period, the temperature of the oxidation furnace will be lower than normal, which leads to poor ammonia oxidation and a reduced conversion rate. This, in turn, results in high levels of ammonium salts in the nitrogen oxide separator; over time, this can cause scaling in the equipment and affect its dynamic balance. Secondly, the various consumptions per ton of acid produced increase.
