Item Diseño de un sistema integral para el manejo del CO2 en la industria cervecera artesanal(Universidad Santiago de Cali, 2025-10-15) Parra Lara, Luis Alejandro; Tusso Pinzón, Ricardo Andrés (Director); Rivadeneira Bolaños, Fabio Eliveny (Director)This research focused on the design, simulation, and optimization of a system for the recovery and storage of carbon dioxide (CO₂) generated during fermentation in microbreweries, with the purpose of reusing it in the carbonation process. Using Aspen Plus software, a system based on chemical absorption with methyldiethanolamine (MDEA) was modeled, achieving a capture efficiency of 99.2% and a purity of 99.9% in the recovered CO₂. Optimal operating conditions including temperature, pressure, and flow rate were evaluated, and key stages such as absorption, solvent regeneration, impurity separation, and flow control were analyzed. The study allowed for a comparison between the volume of CO₂ captured and the actual carbonation needs per production batch, demonstrating the technical feasibility of the system to significantly reduce reliance on external sources. Additionally, international quality standards for food-grade use were identified. The results represent a valuable contribution toward sustainability in the brewing industry, enabling more efficient use of fermentation byproducts and a potential reduction in carbon footprint. This work lays the foundation for future pilot-scale implementations and opens new possibilities for integrating circular economy technologies in small and medium-sized breweries.
