By how much does the flash volume of a high-temperature, high-pressure liquid increase after depressurization? For example: For 1 cubic meter of liquid at 4.0 MPa and a temperature of 210°C, what is the increase in volume when the pressure is reduced to 0.5 MPa at a temperature of 150°C?
Is it the saturated vapor pressure? You can check the corresponding tables
Saturated? Is there a formula or calculation process for that?
At a certain temperature, there is a conversion formula. There are no other cases.
First, it is necessary to know the physical properties of this liquid; thereafter, by calculating the vaporization fraction after flashing, the volumes of the gas phase and the liquid phase can be determined. The vaporization fraction can be calculated manually using the flash equation from chemical engineering principles, or it can be computed using the FLASH module in ASPEN.
