제목 Optimization of CO2 Conversion Process for Methanol Production via Combined Reforming of Methane for minimizing CO2 emission
초록 Utilization of CO2 as a feedstock to produce valuable chemical products is attracting much attention in recent studies. The goal of this work is to minimize a net CO2 emission index (kgCO2/tonMeOH) of a sustainable CO2 conversion process producing methanol via combined reforming of methane reaction which is considered as a prime candidate for commercialization. The process flowsheet of the baseline process is developed using Aspen Plus®, the commercial process simulator. The feedstock ratio and reforming conditions are chosen as the key process design variables.  Sensitivity analysis is used to investigate how their changes influence on CO2 emission flows of the overall process. The optimal values of the four design variables are decided by generating the 2-dimensional equilibrated syngas plot which represents the feasible operating region in consideration of several physical constraints. As a result, 16.3 % reduction of net CO2 emission as well as 7.85 % saving of the operating cost has been achieved with respect to the conventional methanol production.
