초록

본 연구에서는 전력 산업에서 발생하는 폐기물 중의 하나인 Poly Chlorinated Biphenyls(PCBs)를 함유한 절연유를 초임계수 내에서 완전산화반응을 통해서 제거하는 전산모사를 수행하였다. 절연유의 주성분을 노말 데칸으로 선정하였으며, 초임계수 내의 절연유의 함량은 3.0 wt％로 가정하였다. 초임계수 내에서의 물성 추산을 위해서 Peng-Robinson 상태방정식을 사용하였으며, 전산모사를 통해서 초임계수 내에서 3.0 wt％의 절연유 및 과잉 산소가 모두 용해되는 현상을 잘 설명할 수 있었다.

In this study, computer simulations have been performed for the removal of the transformer oil contaminated with polychlorinated biphenyls (PCBs) in supercritical water through complete combustion reaction. We regarded n-decane as a main material of transformer oil, and it is assumed to be 3.0 wt％ of transformer oil in supercritical water. We used Peng-Robinson equation of state to estimate the physical properties of components in supercritical water. Throughout the computer simulation done in this work, we could explain the solubilities of 3.0 wt% of transformer oil and excess oxygen in supercritical water.
