Abstract: Exothermic reversible reactions are industrially important class of processes and many have complex kinetics associated with them. This paper shows how experimentally measured variables such as residence time, temperature and conversion has been used to construct a 3-dimensional attainable region for a typical exothermic reversible reaction without taking into consideration the kinetics associated with the reaction. The experiment was conducted using an adiabatic batch reactor fitted with a thermistor for temperature measurement. The paper also shows how the 2 –dimensional conversiontemperature plot was obtained from the 3- dimensional residence time –temperatureconversion plot. The 2-dimensional plot was then used to propose the optimal process configuration for the process where pre-heating, reaction and mixing allowed. Examination of the boundary of the 2-dimentional attainable region of conversiontemperature plot provided the optimal combination of reaction and mixing and thus optimal reactor structure for a given objective function. The optimal reactor consists of the following reactors in series: a CSTR, a PFR, a differential reactor and a finally another PFR. The paper therefore concludes that in principle without the knowledge of kinetic and information such as optimal temperature profile the attainable region concept can be applied by making use of experimental measured variables such as residence times, temperature and conversion for optimum process synthesis. Hence generating the attainable region using only reaction and mixing from experimental results can provide the design engineer with a benchmark for what can be attained in the system and also how the optimal reactor configuration should look like for any exothermic reversible process.
