Extractive Distillation - an overview | ScienceDirect

Johannes Fink, in Guide to the Practical Use of Chemicals in Refineries and Pipelines, 2016. 11.10.3 Extractive Distillation. Extractive distillation has the advantage that there is a change in the fugacities in a mixture of appropriate components [42].The fugacity is the corrected partial vapor pressure in the mixture. The change in the fugacity is caused there being different repellent

Insights into batch extractive distillation using a -

Extractive distillation has been used for continuous and rectifying batch columns in separating azeotropic mixtures by feeding an extractive agent, normally a high boiler, near the top of the column. Using insights developed for continuous distillation, we compare extractive distillation using the batch rectifier and middle vessel column and
