Research on extractive distillation of binary heterogeneous mixtures
Тонкие химические технологии, 2012 Processes of heterogeneous extractive distillation and extractive distillation with heterogeneous binary mixtures were considered. Entrainers were chosen according to the thermodynamic criterion. The variation of pressure can be used for targeted changes

New extractive configuration separating azeotropic mixture in semi-batch way [PDF]
, 2006 A new variant of batch extractive distillation, the so-called inverse-fed batch extractive distillation is presented. The total amount of the entrainer is pre-loaded to the boiler, and the mixture charge to be separated is continuously fed to the column ...

Generalised model for heteroazeotropic batch distillation with variable decanter hold-up [PDF]
, 2013 A general model of batch heteroazeotropic distillation is proposed. Both liquid phases present in the decanter can be refluxed or withdrawn as distillate, their hold-up can be increased, decreased or kept constant, as well. By assuming maximal separation,

Separation of water – formic acid – acetic acid mixtures in the presence of sulfolane
Тонкие химические технологии, 2019 In this paper, extractive distillation flowsheets for water–formic acid–acetic acid mixtures were designed. Flowsheets not involving preliminary dehydration were considered, and the relative volatilities of the components in the presence of sulfolane ...
