The vapor temperature can be considerate equal to the condensation temperature and the liquid temperature as the boil temperature. When the P temperature is great than boil temperature then, all of F mixture is vapor, and the percent of vapor will be 100% When the P temperature is less than condensation temperature, then all of F mixture is liquid, and the percent of vapor be 0% but, if the P temperature is between the boil temperature and the condensation temperature, then part of F mixture is vapor and other par is liquid. The percent of vapor can be calculated for the following equations : where z_{i} is the molar fraction of each component of the F mixture. k_{i} is the equilibrium constant for the temperature in the P point that it can be considerate equal to the temperature of the F mixture. Vol is the percent of vapor. Then the percent of liquid must (1  Vol ). Vapor flow and liquid flow will be :
R=F*(1Vol) Where : F is the molar flow of the F mixture. The products in D will be calculate with the following equation : where y_{i} is the molar fraction of each component of the D product. z_{i} is the molar fraction of each component of the F mixture. k_{i} is the equilibrium constant for the temperature in the P point that it can be considerate equal to the temperature of the F mixture. Vol is the percent of vapor. The products in R will be calculate with the following equation : x_{i} is the molar fraction of each component of the R product. z_{i} is the molar fraction of each component of the F mixture. k_{i} is the equilibrium constant for the temperature in the P point that it can be considerate equal to the temperature of the F mixture. Vol is the percent of vapor. ONLINE Program Flash Distillation it is more security and easy to use, it has 800 compounds.
