This study investigates the optimization of CO₂ purification within a negative CO₂ emission power plant using a spray ejector condenser (SEC) coupled with a separator. The approach involves direct-contact condensation of vapor, primarily composed of an inert gas (CO₂), facilitated by a subcooled liquid spray. A comprehensive analysis is presented, employing a numerical model to simulate a cyclone separator under various SEC outlet conditions. Methodologically, the simulation, conducted in Fluent, encompasses three-dimensional, transient, and turbulent characteristics using the Reynolds stress model turbulent model and mixture model to replicate the turbulent two-phase flow within a gas–liquid separator. Structural considerations are delved into, evaluating the efficacy of single- and dual-inlet separators to enhance CO₂ purification efficiency.
