Feasibility and sequencing studies for homoazeotropic distillation in a batch rectifier with continuous entrainer feeding
A method has been developed for the assessment of the feasibility and for the sequencing of homoazeotropic distillation in a batch rectifier under continuous entrainer feeding. The method is based on the calculation of the still path and possible composition profiled of the column sections. The application of the method is presented by two examples. In both cases minimum boiling point azeotropic mixtures are separated In the first case a heavy solvent, in the second a light entrainer is used. The most important conclusions were also experimentally verified.
