✦ Synopsis

Chenucal reactors for a smgle exothernuc reverslble reaction wlth mmlmum volume for a @ven duty are conndered m whlch the temperature IS controlled du-ectly by bypassmg cold feed around a mam feed preheater and dlstnbuting It along the length of the reactor, and rn whlch the temperature may not exceed a mven number T In general the optlmal pobcy requlres that m the fir$ part of the reactor the cold feed be added In such a way that the temperature IS mamtaned equal to T, m the second part the rate of addttlon of cold feed must be such that the reactron rate IS maxumzed wlth respect to vanahons of the mass flow rate at eacb pomt (of the second part) of the reactor, and m the last part no cold feed must be added at alt. A numencal example (the commercial nr oxldatlon of SO, to SO,) IS presented
