Always, oil spills do cause serious and dire consequences for the environment, nature, and society that it consumes much time and socio-economic resources to overcome such consequences. Oil spills, hence, posed a big challenge in searching the advanced technologies and devices to recover spilled oil rapidly and efficiently. Indeed, sorbents have been found to play an extremely critical role in the spilled-oil remediation processes. Recently, a large number of various advanced sorbents and sorbent-based oil-collecting devices/technologies have been developed to enhance the oil-recovery capacity. Therefore, it is necessary to have a comprehensive assessment of the application of sorbent-based oil-collecting devices/technologies in recovering spilled oil. Due to this reason, this paper aims to provide a comprehensive review of the advanced technologies of the combination of sorbents and oil-collecting devices in the oil cleanup strategies. Two main oil-collecting devices such as booms and skimmers that could conjunct with sorbents were critically evaluated on the basis of the applicability and technological features, indicating that the capacity of oil spill recovery could achieve 90%. Moreover, oil-storage and oil-collecting devices were also completely mentioned. Last but not least, technical directions, concerns over the application of sorbents in oil recovery, and existing challenges relating to storage, transport, and disposal of used sorbents were discussed in detail. In the future, the automatic process of spilled oil recovery with the conjunction between advanced devices and environmentally friendly high-efficiency sorbents should be further investigated to minimize the environmental impacts, reduce the cost, as well as maximize the collected oil spill.
溢油事故总是会对环境、自然和社会造成严重且可怕的后果，需要耗费大量的时间和社会经济资源来克服这些后果。因此，溢油事故对寻找先进的技术和设备以快速有效地回收溢油提出了巨大挑战。事实上，吸附剂在溢油修复过程中发挥了极其重要的作用。最近，已经开发出大量各种先进的吸附剂和基于吸附剂的集油设备/技术，以提高吸油能力。因此，有必要对基于吸附剂的集油设备/技术在回收溢油方面的应用进行全面评估。出于这个原因，本文旨在对吸附剂和集油设备在油污清理策略中的应用进行全面综述。根据适用性和技术特点，对两种主要的集油设备（如围栏和撇油器）与吸附剂结合的情况进行了批判性评估，结果表明溢油回收能力可达 90%。此外，还完全提到了储油和集油设备。最后但同样重要的是，详细讨论了技术方向、对吸附剂在采油中的应用的关注以及与吸附剂的储存、运输和处置有关的现有挑战。未来，应进一步研究先进设备与环保高效吸附剂相结合的溢油自动回收过程，以最大程度地减少环境影响、降低成本并最大限度地回收溢油。
