초록

본 논문에서는 $300m^3\;h^{-1}$급 수소 생산을 위한 글리세롤 수증기 개질반응에 대해 기술 경제성 평가를 수행하였다. 상업용 공정 설계 프로그램인 Aspen $HYSYS^{(R)}$를 이용하여 글리세롤 수증기 개질반응에 대한 공정을 설계하였으며, 반응온도에 따른 수소 생산량의 차이를 비교 분석하였다. 또한, 항목별 경제성 평가, 민감도 분석, 현금흐름도를 통하여 경제성 평가를 진행하였으며, $300m^3\;h^{-1}$급 글리세롤 수증기 개질반응에서의 수소 생산 단가는 5.10 $ ${kgH_2}^{-1}$로 계산되었다. 수소 생산 단가에 영향을 끼치는 주요 인자를 파악하기 위해 민감도 분석을 실시하였으며, 수소 판매 단가에 따른 현금흐름도 분석을 통해 순현재가치, 할인회수기간, 현재가치율과 같은 다양한 경제성 인자를 파악하였다.

In this paper, the techno-economic analysis of glycerol steam reforming for $H_2$ production capacity of $300m^3\;h^{-1}$ was carried out. The process of glycerol steam reforming was constructed by using Aspen $HYSYS^{(R)}$, a commercial process simulator, and parametric studies for the effect of the operating temperature on $H_2$ production was performed. Moreover, the economic analysis was conducted through an itemized cost estimation, sensitivity analysis (SA) and cash flow diagram (CFD), and the unit $H_2$ production cost was 5.10 $ ${kgH_2}^{-1}$ through the itemized cost estimation of glycerol steam reforming for $H_2$ production capacity of $300m^3\;h^{-1}$. SA was employed to identify key economic factors and various economic indicators such as net present value (NPV), discounted payback period (DPBP), and present value ratio (PVR) were found according to $H_2$ selling price using CFD.
