| Abstract: | The acid-leaching reactor is the key instrument for preparing polyaluminium chloride (PAC) from kaoline,and the continuous-tubular reactor has such merits as benign environment, continuous operation and high utilization factor. The method of calculating the volume of the tubular reactor is studied in this paper. A calculation example is presented. It is found that the factors influencing the volume of the reactor are the initial concentration of hydrochloric acid, the leaching ratio of aluminium oxide, the reaction temperature and the reaction time. With the influencing factors and the suitable operating conditions taken into account, the volume of the reactor is determined. |
