How to calculate the critical pressure and critical temperature of 35% hydrochloric acid?
Isn’t this a liquid? Check the chemical process manual
So how is the specific heat capacity of 35% hydrochloric acid at 82.5°C calculated? It’s not available in the manual.
What is the operating pressure? At 101.33 kPa and 82.5°C, 35% hydrochloric acid exists in a gas-liquid two-phase state, with a vaporization fraction of around 0.4334. At this temperature, the heat capacity of the liquid phase is 3.151 kJ/kg·°C, while that of the gas phase is 0.8152 kJ/kg·°C℃ ； If the operating temperature is maintained at 82.5°C, the pressure for complete liquefaction is 4727 kPa, and the pressure for complete vaporization is 66.31 kPa
