Reasons for the low concentration of wet-process phosphoric acid
Thread Content
The concentration of dilute phosphoric acid produced by the wet process is 24-25%; to meet the requirements for the production of industrial ammonium phosphate, it needs to be concentrated to 45-46%. During the concentration production process, the concentration is too low; therefore, the concentration requirements of the final product can only be met by reducing the load. Solve this issue
To meet the requirements of piston-fed centrifuges in production, ammonium phosphate manufacturers increase its concentration to 45-46% for such applications
The issue lies in the heat exchange efficiency; the device itself can meet the concentration requirements, but the design capacity of the heat exchanger is insufficient
The concentration of dilute acid can be increased to 24-25%, OP – you can message me privately!
