Description
本発明においては、PCBが低濃度に混入するトランスやコンデンサ等の絶縁油を対象として、特殊な吸着剤でなく汎用的な吸着剤と簡便な設備によって絶縁油を精製しようとするものである。つまり、低濃度のPCBを含む絶縁油に関し、微量の水分を含む場合においても、PCB濃度を0.5ppm以下まで吸着除去して低減する方法を提供しようとするものである。
油を吸着容器に室温にて供給し、該吸着容器において該絶縁油の流れ方向の上流部に脱水剤を充填し配置し、下流部に活性アルミナ系吸着剤、活性アルミナシリカゲル系吸着剤、活性ケイ酸マグネシウム系吸着剤のうち少なくとも一つを充填し配置し、該絶縁油と接触させて低濃度ポリ塩化ビフェニル類を吸着除去することを特徴とし、該絶縁油中のポリ塩化ビフェニル濃度を0.5ppm以下にすることを特徴とした絶縁油の精製方法
