Abstract Sulphuric acid plants have been widely used in industrial smelters to reduce sulphur dioxide ( SO 2 ) emissions to the atmosphere. The catalytic SO 2 converter, where SO 2 is oxidized to sulphur trioxide ( SO 3 ), is the key unit and determines the performance of a sulphuric acid plant. In this paper, a dynamic model is built based on mass and energy conservation for the SO 2 converter in an industrial smelter. The derived model is compared with industrial measurement and a very good fit is obtained. A key variable of high industrial interest, SO 2 conversion ratio, is defined and explored in modelling the SO 2 converter, and thus the resulting model is of important industrial values. Based on the derived model, simulations are run to investigate the system dynamics and effects of process variables.
