Green and Sustainable Separation and Purification Technologies

Dear Colleagues,

Green and sustainable separation and purification technologies are an essential aspect of modern chemical engineering, environmental science, and industrial processes. These methods aim to minimize the environmental footprint while maintaining or improving the efficiency of extracting, purifying, and recycling valuable materials from various sources. They focus on reducing energy consumption and minimizing waste generation.

Green and sustainable separation and purification technologies have a wide range of definitions. A typical example is process intensification. This refers to the redesign of existing processes with technologies such as vapor recompression, heat integration, and thermal coupling, thereby reducing their size, improving resource efficiency, and minimizing waste production. Other examples, such as advanced membrane separation technologies, cryogenic distillation technologies, dividing-wall column technologies, reactive distillation technologies, and supergravity distillation technologies, are also included, as long as they contribute to the achievement of green and sustainable chemistry.

By adopting these green and sustainable separation and purification technologies, industries can significantly reduce their environmental impact and contribute to a circular economy by recovering and reusing valuable resources.

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. ChemEngineering is an international peer-reviewed open access semimonthly 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 1600 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.
