Consider genetic algorithms to optimize batch distillation

Alternative simulation tool calculates best reflux conditions to separate binary mixtures

S. MUKHERJEE, R. K. DAHULE, S. S. TAMBE, D. D. RAVETKAR, and B. D. KULKARNI, Chemical Engineering Division, National Chemical Laboratory, Pune, India       Comments? Write: In the petrochemical / chemical industry, batch distillation is an efficient separation tool. The batch mode consumes more energy than continuous distillation; yet, it provides more flexibility and requires less capital investment. Batch-distillation columns can handle a number of components, and its operating conditions can be varied to obtain distillate at the desired purity. Since batch distillation is carried out un
