The thermo dynamics of the HNO3-H2O system are required in numerous chemical and process engineering applications. Knowledge of the composition of the vapour/liquid equilibrium is the basis for the thermal design of the equipment.
The HNO3 module calculates the phase equilibrium and the physical properties of HNO3-H2O systems.
The following physical properties can be determined as a function of pressure, temperature and composition:
- Specific heat capacity
- Dynamic viscosity
- Kinematic viscosity
- Thermal conductivity
- Prandtl number
- Thermal diffusivity
- Surface tension
- Coefficient of thermal expansion
- Saturation pressure
- Partial pressure of water and acid
The data on which it is based are determined or interpolated from data tables and can be extended with measurement data.
