... RSI indicates that the reactor should be able to handle upsets better than the reactor designed for 353 K operation. However, depending on the magnitude of the disturbances and other parameters, ... values of RSI for three design conversions as functions of reactor design temperature. It is clear that higher temperature and lower conversion increase the value of RSI and therefore imply worse ... DT driving force to handle upsets, so we anticipate that temperature control will be poor. For a design reactor temperature of 320 K, the reactor is much larger (75.8 m 3 ) and the heat transfer...
