Microwave regeneration of adsorbents facilitates the recovery of volatile organic compounds (VOCs) by decoupling the bed heating from the stripping gas. This makes possible the creation of a highly-concentrated regeneration effluent from which the VOCs can be recovered by condensation at near-ambient temperatures. The economic feasibility of two novel microwave-regenerated adsorption systems was evaluated by systematically comparing the capital and operating costs of the proposed systems with 10 conventional VOC control technologies. The microwave systems were found to have similar capital and operating costs to conventional steam regeneration systems and, therefore, may present an attractive alternative for recovering water-miscible solvents. In general, the cost of the microwave subsystem is a relatively small component of the overall system costs, and the microwave power requirements are within the range of commercially available generators, even for large emission streams.
吸附剂的微波再生通过将床层加热与汽提气解耦，促进了挥发性有机化合物（VOCs）的回收。这使得能够产生高浓度的再生流出物，从中可以通过近环境温度下的冷凝来回收VOCs。通过系统地比较所提出系统与10种传统VOC控制技术的资本成本和运营成本，评估了两种新型微波再生吸附系统的经济可行性。发现微波系统的资本成本和运营成本与传统蒸汽再生系统相似，因此，对于回收与水混溶的溶剂可能是一个有吸引力的替代方案。一般来说，微波子系统的成本在整个系统成本中所占比例相对较小，即使对于大型排放流，微波功率需求也在市售发生器的范围内。
