WebbThis form of the balances works equally well for the reboiler. Knowing the boilup ratio (Vn/B) is very useful for that balance set. If we start our procedure at the reboiler, we know that determining whether the vaporization is partial or total will allow us to relate x B to x 6. WebbIn this case, reflux ratio and distillate to feed ratio where chosen as the operating specifications in the Setup dialog box. Reflux ratio will vary as the program attempts to meet the design specifications of 97.5% molar purity in each of the distillate and bottoms feeds. The following procedure outlines how to make such specifications: 1. WebbFor this simulation we will be inputting the reflux ratio, the key component recoveries, and the tower pressures.
