I'm currently doing a design for my final year studies and it's regarding esterification process. My proposed reactor is CSTR, operating at a temperature of 60C and 400 kPa. Reactants are methanol and jatropha oil with sulphuric acid catalyst. For a commercial scale production of biodiesel, since this is an endothermic reaction, how do I maintain the temperature of the reactor? Using cooling jackets will not give uniform heat distribution for large reactors, so what other alternatives do I have?
