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.
