Special Issue Information
Dear Colleagues,
The distillation process is the cornerstone of chemical engineering, and with the introduction of new solvents and innovative methods, significant progress has been made in the distillation process. These developments aim to improve separation efficiency, reduce energy consumption, and enhance product purity. New solvents, such as ionic liquids and deep eutectic solvents, have unique properties such as low volatility, high thermal stability, and adjustable polarity, which can be used to optimize distillation processes. In addition, methods such as extraction distillation, azeotropic distillation, and pressure swing distillation are being improved to handle complex mixtures and challenging separations. For example, extraction distillation uses solvents to alter the vapor–liquid equilibrium and promote the separation of near-boiling-point compounds. Azeotropic distillation uses entrainers to break up azeotropes, while pressure swing distillation utilizes different boiling points at different pressures to achieve separation. These novel methods not only address traditional limitations but also pave the way for more environmentally friendly and sustainable distillation practices. In this Special Issue, we hope to collect the latest research progress in new distillation technologies and solvent-related fields to promote the development and prosperity of the distillation industry. I hope this Special Issue can provide an opportunity for researchers in this field to showcase their research findings.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
