Roaster off-gas systems play an important role in reducing SO2 emissions to the atmosphere and in ensuringthe satisfactory operation of nickel smelters in accordance with environmental regulations. In this paper, thedynamic models for an industrial roaster off-gas system are developed using mass continuity, momentum,and energy conservation laws. Industrial measured pressure data are compared with the steady-state pressuremodels that are the special case of the developed dynamic models, and good agreement is obtained. On thebasis of the developed dynamic models, the effects of important variables on the dynamics of the off-gassystem are studied via simulations. The developed dynamic models provide a necessary basis for highperformance control development for roaster off-gas systems.
