摘要：

As the trend to speciality chemicals continues to emphasize batch processing plants, the need for a quick, easy-to-use method for designing batch distillation columns becomes more important. Both the non-steady-state conditions and the nonlinearity of batch distillation make it difficult to derive analytical design formulas except for very basic and overly simplified systems. This paper presents a method for determining preliminary shortcut economic designs for both binary and ternary batch distillation columns. Design correlations are given that can be used to easily read off the optimum number of trays and the optimum reflux ratio for a given separation: specified relative volatilities, product purities, energy cost, and material of construction.
