Separation chamber and heating chamber of a single-effect evaporator

This post was last edited by cainiao_*ng on 2011-3-10 13:43. Is there any relationship between the pressure in the separation chamber and the pressure in the heating chamber? How do we determine these two pressures?
The pressure in the heating chamber is generally kept below 0.1 MPa; it can also be set to 0. For pressures above 1 MPA, it depends crucially on what you are evaporating. The pressure in the separation chamber is generally evacuated, which facilitates evaporation separation
First, determine your feed temperature, discharge temperature, as well as the pressure difference across the heater and separator – in other words, the effective temperature difference of the system. You need to decide these values based on your specific material
