5 Feasible Ranges oe Distillate Composition and Bottoms Rate [Pg.230]

The following applications illustrate some of the factors considered in the validation of a column design using graphical representation. [Pg.231]

A distillation column is designed for separating methanol from a methanol-water mixture containing 60% mole methanol. The overhead methanol product must have a purity of 98% mole, and the methanol in the bottoms should not exceed a concentration of 4% mole. The column operating pressure is 100 kPa, with the feed entering the column at its bubble point. It is proposed to design the column at a reflux ratio of 1.0, or an /.,/ / ratio of 0.5. [Pg.231]
