Special Issue Information

Dear Colleagues,

Aimed at testing the outstanding properties associated with new generation solvents (ionic liquids, deep eutectic solvents and natural solvents, among others), the main field of research is the development of advanced separation processes. Overall, new-generation solvents have been proven to be effective in the separation of gases, liquids, and solids and have created the development of new advanced separation processes in many different fields. These compounds have shown noticeable features as solvents for a high number of liquid–liquid extraction or extractive distillation processes, that is, hydrocarbons and water-containing mixtures, while they have also allowed for the development of knowledge about carbon capture and utilization technologies, mainly through CO2 absorption and adsorption processes, following chemical and physical sorption directly using them or by designing hybrid advanced materials. Furthermore, the use of new generation solvents deals with effective pretreatments to fractionate biomasses, helping biorefinery to achieve the current standards. In this content, it is necessary to combine and analyze the wide applications and the designer solvent character known for different solvent classes, together with all of the new advanced separation proposals, in order to merge ideas and make knowledge in the field more robust.

This Special Issue on “Advanced Separation Processes Based on New-Generation Solvents” aims to collect high-quality research articles addressing new advanced separation processes, relevant insights to well-known IL-based separations, and comprehensive review studies in well-explored topics with special interest. Topics include but are not limited to the following:

- Extraction and extractive distillation processes using new generation solvents;

- Absorption or adsorption of greenhouse gases using new generation solvents or advanced materials combined with them;

- Biomass pretreatment and fractionation with new generation solvents;

- Lab-scale specific uses of new generation solvents for separation purposes;

- Product isolation and new generation solvents recovery/regeneration;

- New generation solvents and process stability in representative operating cycles;

- Feasibility and economic analyses of whole advanced separation processes with new generation solvents.

Diverse and abundant applications of the eutectic solvents have appeared in the last years. Their promising tunable properties, eco-friendly character and the possibility of being prepared from numerous compounds have led to the publication of numerous papers addressing their use in different areas. Terpenes and terpenoids have been employed in the formulation of eutectic solvents, though they also have been applied as solvents in extraction processes. For their hydrophobic nature, renewable character, low environmental impact, cost and being non-hazardous, they have also been proposed as possible substitutes of conventional solvents in the separation of organic compounds from aqueous streams, similarly to hydrophobic eutectic solvents. The present work reviews the application of eutectic solvents in liquid–liquid extraction and terpenes and terpenoids in extraction processes. It has been made a research in the current state-of-the-art in these fields, describing the proposed applications of the solvents. It has been highlighted the scale-up feasibility, solvent regeneration and reuse procedures and the comparison of the performance of eutectic solvents, terpenes and terpenoids in extraction with conventional organic solvents or ionic liquids. Ultimately, it has been also discussed the employ of predictive methods in extraction, the reliability of thermodynamic models in correlation of liquid–liquid equilibria and simulation of liquid–liquid extraction processes.
