Behavior of heat removal unsteady state SO2 converters (1): Stability of the unsteady state SO2 converter

Based on the software used in the simulation calculation of unsteady state SO2 converter, a comparison between two types of unsteady state converter, namely, heat removal and adiabatic converter is presented. The effects of parameters such as gas concentration, velocity, cycle duration and cooling capacity on unsteady state SO2 converter were studied. For the gas of high concentration, two-point heat removal structure was recommended. With identical gas concentration, traveling wave velocity is directly proportional to gas velocity. For two-point heat removal converter, cooling capacity and cycle duration are two controllable variables in optimizing the reaction, whereas the inlet temperature of gas and preheated temperature of catalyst bed have relatively minor effect on unsteady state conversion.
