Binary Distillation (Part 2)

Review Of Binary Distillation – McCabe-Thiele By Computer (Part 2) – Two-Feed Distillation

In our first paper we presented a BASIC computer program for performing the McCabe-Thiele (1) theoretical stage step-off procedure for a single feed – two product binary distillation column. We emphasized application to close boiling separations such as for splitter fractionators where the operating and equilibrium lines (curves) are generally quite close together and where nearly constant molal overflow prevails.

In this second installment we extend the computer program to handle a two feed – two product distillation column and also incorporate the capability to calculate theoretical tray temperatures. In principle this procedure could be applied to any number of feeds where a large number of intermediate operating lines are involved.
