Abstract Amine solvents were chemically desorbed by the semi-dry desulfurization slag (DFS) and showed cycle stabilities. With the comparison of the absorption and mineralization properties of four commonly used amines, such as MEA、DEA、MDEA and AMP, AMP was selected as the absorbent for the process. The effects of particle size, stirring speed, amine concentration, and reaction temperature on the mineralization reaction were investigated. The surface coverage model was used to dynamically fit the experimental data and the materials and energy consumption of the overall process were calculated. The results show that the absorption-mineralization process with DFS had advantages over the thermal regeneration process in terms of energy consumption and cost.
