Thermodynamic Modeling of Calcium Sulfate

2019-11-5 · Calcium sulfate is one of the most common inorganic salts with a high scaling potential. The solubility of calcium sulfate was modeled with the Pitzer equation at a temperature range from 273.15 to 473.15 K from published solubility data, which was critically evaluated. Only two Pitzer parameters, β(1) and β(2), with simple temperature dependency are required to model the solubility with

Forbes Marshall > Knowledge > Energy Conservation

If the outlet steam temperature is, say,15 deg.C higher than saturation temperatures of180 deg.C, then the steam consumption shall be 10900 Kgs/Hr to achieve the same enthalpy transfer. This means that you will end up spending 900 kgs/Hr steam extra due to the system inefficiency.

Introduction To Food Engineering, Fourth Edition - ID

Saturation temperature is the temperature at which vaporization takes place at a given pressure. This pressure is called the saturation pressure. Thus, water at 100 C has a saturation pressure of 101.3 kPa. When the temperature of the vapor is greater than the saturation temperature at the existing pressure, it is called superheated vapor.
