Phosphorus chemical process technology
Thread Content
There is a dilute phosphoric acid concentration unit (single-effect evaporation). The temperature of the liquid at the interface of the evaporation chamber is 81 degrees, the vacuum level is 66 KPa, and the local atmospheric pressure is 82 KPa. May I ask: how can experts determine whether the gas and liquid in the evaporation chamber are in a boiling state? (Evaporation chamber ignores mirrors), (judged from operation and theory)
Theoretically: Determination is based on the material composition and vapor-liquid equilibrium relationships. Practically: Steam consumption, the presence or absence of condensate, etc
