The study aims to develop alternative models for dual production of methanol and H-2 using Aspen Plus, with a focus on controlling greenhouse gas emissions. Comparison between the base case and alternative case shows that the alternative model offers higher process efficiency, lower energy requirements, reduced fuel production costs, lower CO2 emissions, and better project feasibility.
( )The rise in global energy requirements and greenhouse gas emissions demands for the development of cleaner fuels with the reduction in CO2 emissions. Methanol and H-2 are considered as cleaner fuels, which are vastly used in my process and product base industries due to excellent combustion properties. This study aims to develop the alternative models using Aspen Plus for dual production of methanol and H-2 with the control on greenhouse gas emissions. The base case model represents the coal to methanol and H-2 production process, whereas, the alternative model presents the process integration approach to integrate the state-of-art coal gasification and natural gas reforming models to utilize the key technical benefits for each technology. Both the models are techno-economically compared in terms of methanol and H-2 production rates, specific energy requirements, carbon conversion, CO2 specific emissions, overall process efficiencies, fuel production costs and project feasibilities. The results showed that the case 2 design offers 4.28% higher process efficiency and 18.3% reduction in specific energy requirements (GJ) for each metric ton (MT) of fuel (methanol and H-2) production compared to the base case. Moreover, fuel production cost (sic/MT) for the case 2 design is also 13% lower compared to the case 1 design. The comparative analysis also showed that the case 2 design reduces the CO2 specific emissions up to 34.3% compared to the case 1 design. Due to the higher process performance and lower production costs, case 2 design also showed the better project feasibility compared to the base case design.
