The most important developments in solvent-based fluid separations, separations involving at least one fluid phase, are reviewed. After a brief introduction and discussion on general solvent trends observed in all fields of application, several specific fields are discussed. Important solvent trends include replacement of traditional molecular solvents by ionic liquids and deep eutectic solvents and, more recently, increasing discussion around bio-based solvents in some application fields. Furthermore, stimuli-responsive systems are discussed; the most significant developments in this field are seen for CO2-switchable and redox-responsive solvents. Discussed fields of application include hydrocarbons separations, carbon capture, biorefineries, and metals separations. For all but the hydrocarbons separations, newly reported electrochemically mediated separations seem to offer exciting new windows of opportunities. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 12 is June 2021.

基于溶剂的流体分离的最新进展。

回顾了基于溶剂的流体分离的最重要进展，即涉及至少一种流体相的分离。在简要介绍和讨论在所有应用领域中观察到的一般溶剂趋势之后，将讨论几个特定领域。重要的溶剂趋势包括用离子液体和深共熔溶剂代替传统的分子溶剂，最近，在某些应用领域中，有关生物基溶剂的讨论也越来越多。此外，讨论了刺激响应系统。对于二氧化碳可转换和氧化还原响应型溶剂，该领域的最重要进展是可见的。讨论的应用领域包括碳氢化合物分离，碳捕集，生物精炼和金属分离。除了碳氢化合物的分离以外，新近报道的电化学介导的分离似乎提供了令人兴奋的新机会。《化学和生物分子工程年度评论》第12卷的最终最终在线发布日期为2021年6月。有关修订的估算，请参见http://www.annualreviews.org/page/journal/pubdates。
