Abstract: (54 Views) |
Given the growing energy crises and environmental concerns, this study investigates and optimizes a hydrogen production system based on the gasification of sugarcane bagasse biomass. To this end, a comprehensive quadruple (4E) analysis, comprising energy, exergy, economic, and environmental assessments, was conducted. The proposed system consists of a drying unit, a gasifier, a water-gas shift reactor, and a hydrogen separator. The primary objective was multi-objective optimization to maximize energy and exergy efficiencies while simultaneously minimizing the total cost rate and carbon dioxide emission rate, utilizing the Bee Algorithm. The initial analysis of the system indicated an energy efficiency of 37.62% and an exergy efficiency of 15.28%. Following the optimization process, these efficiencies increased to 41.62% and 19.17%, respectively, while the total cost and CO₂ emissions were reduced. Furthermore, a sensitivity analysis revealed that increasing the syngas temperature and decreasing the biomass moisture were the most effective parameters for enhancing system performance without adverse economic or environmental consequences. |
