Abstract

This study was carried out to investigate physical and chemical characteristics of the distillates and residue of Athabasca oilsand bitumen obtained from Canada, using a vacuum distillation unit. The distillates and residue produced from the vacuum distillation were characterized through atomic analysis, SARA analysis, and measurement of boiling point distribution, molecular weight, and API gravity. The vacuum distillation equipment consisted of a 6-litter volume vessel, a glass-packed column, a condenser, a reflux device, a flask fer collecting distillates, and a temperature controller. The cutting of distillates was performed with four steps under the condition of full vacuum and maximum temperature of $320^{\circ}C$. The results showed that the sulfur amount and average molecular weight of the distillates were significantly reduced compared to those of oilsand bitumen. As the cutting temperature increased, the hydrogen amount decreased but the sulfur amount and average molecular weight increased in the distillates.

본 연구는 감압증류장치(Vacuum Distillation Unit)를 이용하여 캐나다산 아사바스카 오일샌드 역청 (Athabasca Oilsands Bitumen)의 증류액(Distillates)및 잔사유(Residue)에 대한 물리화학적 특성변화를 살펴보기 위하여 수행되었다. 감압증류장치를 이용하여 생성된 증류액 및 잔사유의 원소분석, SARA 분석, 비점분포 분석, 분자량 측정, API 비중 등을 측정하였으며, 감압증류실험장치는 6 l 용량의 Vessel, 충진컬럼, 응축기, 리플럭스, 증류액 포집플라스크, 온도제어장치 등으로 구성되었다. 증류액의 구분 조건은 최대 감압 및 최대 $320^{\circ}C$의 승온조건 하에 총 4단계로 수행되었다. 분석 결과 오일샌드 역청에 비해 증류액의 황분 및 평균분자량은 현저히 감소하였다. 증류액의 온도가 고온으로 갈수록 증류액의 수소함량은 감소하고, 황 함량 및 평균분자량은 증가하는 경향을 보였다.
