Abstract
The steady-state design of a two-column azeotropic distillation system operating at two different pressures was studied with the objective of reducing energy consumption. The minimum-boiling, homogeneous binary azeotropic system tetrahydrofuran-water was used as a specific example. Energy consumption was reduced by a factor of 2 from conventional designs by using heat integration and feed preheat and by optimizing column pressures and overhead purities. The dynamics and control of the two-column, heat-integrated system was also explored. A control system was developed that effectively handled a variety of disturbances without any severe interactions between columns.
