A theoretical study on the spray drying absorber in an HC1 removal process by lime slurries has been performed with a mathematical model which describes heat and mass transfer and fluid flows in the absorber. From heat and mass balances and a force balance for a moving droplet in the absorber, a set of first-order, nonlinear differential equations relating the amount of water, the gas and droplet temperatures, the drop velocity, the HC1 partial pressure, etc., along the axial direction of the tower was formulated. These relationships were numerically solved to give characteristic profiles in the tower. The results of the simulation based on this model were compared with experimental data and showed satisfactory agreement.
