Better design for ternary distillation detailed

Article Abstract:

Air Products and Chemicals Inc's chemical engineers, Zbigniew T Fidkowski and Rakesh Agrawal, have developed a series of ternary distillation columns that can often replace more conventional, thermally coupled systems of columns. Fidowski and Agrawal found that control problems can be lowered with fewer interconnecting streams, citing the difficulty in controlling fully coupled system for distillation columns for ternary separations, mainly because of the two, two-way links between columns.

Distillation

Article Abstract:

The distillation column should be designed with a small margin for operational variability. The advanced options such as dividing wall, heat-pumped and pressure-staged that can be used to establish the optimum design procedure for a standard distillation column are stated.
