ACETONE RECOVERY USING BATCH DISTILLATION

Comparison of Extractive and Pressure-Swing Batch Distillation for Acetone-Methanol Separation

The performance of extractive (BED) and pressure swing distillation (PSBD) for the separation of the mixture acetone(A)-methanol(B) forming a minimum azeotrope are compared. For the BED, where the solvent(S) is water, three different operational policies (basic, modified, controlled) are studied. For the PSBD the double column batch stripper (DCBS) is applied with and without heat integration (...

Tools for Teaching Batch Distillation Inductively using Process Simulation

One approach to active learning involves taking students through a guided exploration process; one which ensures students will observe phenomena and then be asked questions intended to draw conclusions regarding the observations. In recent years, this has been called inductive teaching, but more recently the expression “inquiry-based instruction” or related terms have become more common. Concur...

Comparison of Regular and Inverted Batch Distillation

-Several alternative strategies have been suggested to increase the productivity of batch distillation. One is the use of inverted columns where the feed is charged to the condenser drum instead of to the reboiler as for regular columns. In the first part of this paper, optimal results in terms of minimum operating time for separations in a regular and an inverted batch column are presented. Th...
