Abstract

To date the management of digestate is a crucial task for anaerobic digestion process. In the present work a strategy for digestate management is thermodynamically analyzed by a commercial software for process simulation called CHEMCAD®. Pyrolysis of digestate is simulated by a minimization of the free Gibbs energy. The sequestration of the carbon dioxide (CO₂) released by the pyrolysis is investigated by the addition of calcium oxide, in order to reduce CO₂ emissions. The effect of the pyrolysis temperature between 400–900 ℃ and of the CaO/digestate mass ratio between 0–0.5 was discussed, as well. The CHEMCAD application allowed to investigate the chemisorption behaviour by focusing on the temperature-dependent CO₂ sorption trends in relation to different values of the CaO mass ratio. Temperature below 650 ℃ should be considered for CO₂ sorption by CaO. CO₂ molar fraction below 10% was obtained for temperature below 450 ℃ and CaO/digestate mass ratio higher than 0.4.
