文摘

•: Oil shale ash could be utilized as a low-cost source of lime for PCC production.
•: The dissolution mechanisms and kinetics of Ca(OH)₂ and CaSO₄·2H₂O were investigated.
•: Reaction rate constants for Ca(OH)₂ and CaSO₄·2H₂O dissolution were determined.
•: The kinetic models were implemented within the Aspen Plus simulation platform.
