Ammonia escape mass transfer and heat transfer characteristics of CO2 absorption in packed absorbing column

摘要: Ammonia escape is one of the main barriers to CO2 capture by aqueous ammonia solution, so it benefit practical engineering clarify effects running parameters on mass transfer and heat performance in packed absorbing column. Based representative elementary volume approach pseudo-single-liquid model, a computational model for solution an industrial column developed, which fractions temperatures, coefficient per unit are obtained. The results show that volumetric mainly influenced liquid inlet temperature flow rate, fraction rate. What’s more, concentration plays key role amount, greatly dominated gas rate temperature. This work can contribute inhibition high removal efficiency application columns.
