Abstract
In this study, we propose using liquefied natural gas directly to steam methane reforming processes and compare the proposed system with the natural gas steam methane reforming process. To analyze the effectiveness of the proposed system, a simulation model was constructed using MATLAB and the Cantera thermodynamic tool, and the balance of plants comprised a dimensionless model. It was confirmed that the proposed system can reduce the work done by the system, and thus, the efficiency of the system is improved. When the system operating pressure increases, the work done by the hydrogen compressor decreases, and the system efficiency decreases with reducing amounts of produced hydrogen. In addition, it was confirmed that the amount of greenhouse gas emissions in the liquefied natural gas system is smaller than that of natural gas system.
