Abstract

This study investigates the feasibility of applying a cross-flow rotating packed bed (RPB) to absorb carbon dioxide (CO₂) by mixed amine solutions from gaseous streams. The cross-flow RPB has an inner radius of 2.4 cm, an outer radius of 4.4 cm and an axial height of 12.0 cm. Wire mesh was used as packings. Rotor speeds ranged from 600 to 1800 rpm, providing 14-123 equivalent gravitational force. The removal efficiency of CO₂ was determined at various values of operating parameters, including the rotor speed, gas flow rate, mixed amine flow rate, and absorbent type. Our experimental results demonstrated that the removal efficiency of CO₂ increased with the rotor speed and mixed amine flow rate, however, decreased with the gas flow rate. Furthermore, CO₂ removal efficiency using PZ/MEA was superior to those using MEA and AMP/MEA. Consequently, PZ/MEA could be used in a cross-flow RPB for the removal of CO₂ from the gas stream with higher flow rate owing to its high efficiency and its low cost.
