New member seeking help with the calculation of flash vapor volume
Thread Content
It is known that the condensate flow rate is 100 T/h, and the pressure of the condensate corresponds to that of saturated water at 2.0 MPa(a); the pressure of the flash vapor obtained after flashing is 0.1 MPa(a). How to calculate the flash volume? What is the temperature of the water discharged after flash evaporation?

Material balance: The amount of vapor generated through flashing plus the amount of water after flashing equals 100 t/h； Energy balance: The amount of condensate multiplied by its enthalpy is equal to the amount of flash vapor (saturated steam) multiplied by its enthalpy, plus the amount of water after flashing multiplied by the enthalpy of that water (saturated water) ； All the quantities corresponding to one solution of this system of equations have been calculated. The temperature of the drainage is the temperature of saturated water at 0.1 MPa.
Thank you, I now know how to calculate it. Aspen is quite expensive, right?~~
