In the current energy transition towards sustainable energy resources, H₂S, a byproduct of the oil and gas industry, is considered a promising alternative source of sustainable H₂ production. H₂ can be produced from H₂S by H₂S-methane reforming (H₂SMR), which serves as an alternative process for the commercial production of H₂ with valuable side products such as carbon disulfide (CS₂) and sulfur. This study focuses on the rigorous process modeling of the H₂S-methane reforming process to determine the thermodynamic feasibility and system performance of the process. A comprehensive sensitivity analysis of various operating conditions, including reaction temperature and H₂S-methane feed ratio, is evaluated to analyze their effect on reactant conversion and hydrogen yield, along with byproduct formation. Preliminary results indicate that the higher temperature significantly enhances methane conversion due to the endothermic nature, and the feed ratio is crucial for managing the side product production. These findings highlight that the optimization of these reactor designs is crucial in improving the economic viability of H₂S-based hydrogen production for commercial applications.
