Efficient separation method for tert-butanol dehydration via extractive distillation
Ka-Man Lo,I-Lung Chien +1 more
TL;DR: In this article, an efficient separation method for tert-butanol dehydration via extractive distillation is investigated, where the heavy entrainer used is glycerol, a non-toxic byproduct in the production of biodiesel, is less expensive and more environmentally friendly than other conventional entrainers.

Design and Control of Dividing-Wall Column for tert-Butanol Dehydration System via Heterogeneous Azeotropic Distillation
TL;DR: In this paper, a three-column model of azeotropic dividing-wall column (A-DWC) for heterogeneous aZEotropic distillation (HAD) is investigated by demonstrating the design and control of tert-butanol (tbutanol) dehydration using cyclohexane as entrainer, which can solve disturbance issues and maintain the product purities very close to the set points with small deviation and short settling time.

Application of Vapor Recompression to Heterogeneous Azeotropic Dividing-Wall Distillation Columns
TL;DR: In this paper, the feasibility and effectiveness of reinforcing the HADWDC with the vapor recompression heat pump (VRHP) are examined. And a systematic procedure is developed to effectively determine the optimum combination of the VRHP and the HADEWDC in order to minimize the total annual cost.

Local compositions in thermodynamic excess functions for liquid mixtures
Henri Renon,John M. Prausnitz +1 more
TL;DR: In this paper, a new equation based on Scott's two-liquid model and on an assumption of nonrandomness similar to that used by Wilson is derived, which gives an excellent representation of many types of liquid mixtures.
