In light of the elevating pressures toward adopting intensifying technologies, centrifugal extractors are increasingly drawing attention as a promising alternative to traditional extraction equipment. Recently, many fields have applied them in research and that resulted in a considerable amount of information that may be hard to follow. To keep interested researchers updated, this work presents the state-of-the-art status of those devices. That is, the different types of centrifugal extractors are first surveyed with emphasis on those available on the market nowadays. Then, their recent applications are covered with exclusion of two fields: oil-water separations and nuclear industry, as the purpose is to accent centrifugal extractors' potential and compatibility with the widest possible range of applications beyond traditional ones. A further section addresses the hydrodynamics of annular centrifugal contactors that form a major subfamily of centrifugal extractors. Those annular variants have received special focus throughout this work, since not only are they the most encountered devices in literature but also still to date under development with latest versions being 3D-printed.

液-液离心萃取器：类型和最近的应用——回顾

鉴于采用强化技术的压力越来越大，离心提取器作为传统提取设备的有前途的替代品越来越受到关注。最近，许多领域已将它们应用于研究，并产生了大量可能难以理解的信息。为了让感兴趣的研究人员了解最新情况，这项工作展示了这些设备的最新状态。也就是说，首先对不同类型的离心提取器进行了调查，重点是当今市场上可用的那些。然后，它们最近的应用被排除在两个领域之外：油水分离和核工业，因为其目的是强调离心提取器的潜力和与传统应用之外的最广泛应用的兼容性。另一部分讨论了环形离心接触器的流体动力学，该接触器形成了离心提取器的主要亚族。这些环形变体在这项工作中受到了特别关注，因为它们不仅是文献中遇到最多的设备，而且迄今为止仍在开发中，最新版本是 3D 打印的。
