감압증류에 의한 석유정제 상압잔사유와 폐윤활유의 혼합처리 및 공정모사
Process Simulation and Vacuum Distillation of Petroleum Atmospheric Residuum with Waste Lube Oils
황종식, 김형락, 김명수
자동차용 내연기관에서 발생하는 폐윤활유를 석유정제 중질유분인 상압잔사유와 배합한 후 고비점 진증류(TBP) 장치를 이용한 감압증류실험을 통해 재정제함으로써 폐유 내 존재하는 유해물질들의 제거효율을 평가하였다. 본 실험을 통해 고품질의 정제연료유분과 아스팔트를 얻었으며 페유 내 중금속, 회분 그리고 잔류탄소분의 95% 이상이 감압잔사유쪽으로 제거되었다. 상압잔사유분에 대한 페유의 혼합비율을 0-20%까지 변화시키면서 수행된 감압증류실험을 통해 폐유 혼합비가 증가함에 따라 정제연료유분의 수율 증가와 물성개선 효과가 입증되었다. 이러한 실험결과는 PRO II를 이용한 공정모사 결과 값과도 잘 일치된 결과를 보여주었다.
The removal efficiency of the contaminated constituents existing in the waste automobile lube oils mixed with petroleum atmospheric residues during a re-refining process was investigated by a vacuum TBP distillation. The refined fuel oils and asphalts with higher qualities were obtained by this process and more than 95% of heavy metals, ash and carbon residue contents in the waste lube oils were eliminated to vacuum residues. The increased yield and improved quality of distilled products were identified in the range of 0-20% blending ratio of waste lube oils to atmospheric residues. These experimental results showed the reasonable agreements with the calculated values provided by process simulation using PRO II.
