SIMULATION OF REMOVAL OF HCL-GAS IN A SPRAY DRY TOWER

A mathematical model of the absorption of HCl gas-in a spray dry tower has been proposed. The proposed model describes the mechanism of HCl removal taking into account the atomized droplet size distribution and the change in the droplet state from ''slurry droplet'' to ''dry part icle''. It is found that the removal efficiency can be simulated by us ing the model with the constant mean diameter of droplet from the simu lation results. Simulation results of the removal of HCl gas are in go od agreement with the experimental data in a spray dry tower.
