Technical and economical pre-feasibility for ethanol production from CO2 electroreduction
Article Sidebar
Main Article Content
At present, the technical and economical pre-feasibility of electrochemical reduction from CO2 to ethanol is unknown. This creates the challenge of mitigating the environmental impact of greenhouse gases. This study presents a model to obtain fuel alcohol from carbon dioxide with Aspen Plus V11 simulation software, utilizing both, the experimental parameters established by Yuan (1), and the scaling of an industrial plant which processes 226,12 Ton of CO2 per day. The kinetic equation for the liquid phase of s-1 was determined as well as its conditions of operations, allowing the acquisition of 98,74% of conversion, 8,85% of selectivity, 99% ethanol flow at 4.390,18 kg/h and hydrogen Flow at 1.828,96 kg/h. From the cost estimation, the viability of the project was determined with a 85,18% IRR and an investment return of 2,20 years after initiating the project. In conclusion, the use of an electrochemical process to produce fuel alcohol from carbon dioxide was found to be viable economically and industrially
