Abstract

This work is concerned with customization of the existing electrolyte thermodynamic model for process simulation and experimental studies on the sulfuric acid decomposition process of the SI cycle, using a commercial steady state simulator. An electrolyte thermodynamic model for the sulfuric acid-water system was tailored with four candidates available in commercial software, utilizing data from Perry's Handbook. Simulation of the sulfuric acid decomposition process comprising a flash separator, distillation column and decomposer was validated with the experimental results. To facilitate the lumped-parameter steady-state model-based simulation of sulfuric acid decomposition, the decomposer was conceptually decoupled into three sections: evaporation, H2SO4 dissociation, and SO3 catalytic reduction to SO2. The process simulation results exhibited good agreement with experimental data. This work contributes to future work on simulation and experimental study of a scaled-up process system and exergy analysis for an optimal energy-efficient sulfuric acid decomposition process in the SI cycle.
