The composition of the raw material is 60 mol% benzene, 40 mol% toluene, and the flow rate is 100 kmol/h. The temperature and pressure conditions
The composition of the raw material is 60 mol% benzene, 40 mol% toluene, and the flow rate is 100 kmol/h. The temperature and pressure conditions of the raw material solution are 100oC and 350 kPa. In this case, when the operating conditions of the flash drum are 100oC and 120 kPa, determine the following through numerical calculation. However, use the Antoine vapor pressure estimation formula based on the temperature of the pure ingredients given in the table below.
1. When the mole fraction value of steam changes from 0 to 1 at intervals of 0.001, calculate the change in the mole fraction value of steam using Excel, and plot it.
2. Calculate the mole fraction of steam on the flash drum to the fourth decimal place.
3. Calculate the molar flow of steam and liquid flow to the second decimal place in kmol/h.
4. Estimate the mole fraction of each component in the vapor phase and liquid phase to the fourth decimal place.
