Abstract
Vacuum heating separation is one of the methods for removing PCBs from electric appliances, whereby PCBs are vaporized under vacuum condition at 200°C. This method has a high removal performance without deteriorating the insulation oil, PCBs and other components of pole transformers. However, it takes a long time to detoxify pole transformers, because they are heated by radiative heat transfer in a vacuum. Previously, we reported that the heating time for vacuum heating separation was shortened by using a vibration dryer. In this study, the fundamental performance of PCB removal from various samples by the vacuum heating method was investigated. As a result, PCBs were reduced below the removal standard from copper and insulation paper. PCB concentration in the activated alumina was reduced by extending the treatment time.
