The RMProcess for methanation of coal syngas, which consists of six fixed-bed, adiabatic, catalytic reactors connected in series with interstage waste-heat boilers and feedwater preheaters to remove the heat of reaction, was successfully simulated dynamically using a mixed ordinary/partial differential equation model. Computer integration of the-model was accomplished using the numerical method of lines. Controls were added to the model to regulate the temperature of the gas feed into the reactors by diverting some gas around the interstage heat-exchangers. It was found that the controller selection and tuning, although generally not a goal in large-scale simulations, was quite important. Conventional methods used to tune the controllers gave controller settings that caused a significant detrimental effect on numerical integration stability and efficiency. |
