This paper presents the exergy analysis of an industrial plant for the production of sulfuric acid. We give a brief description of the process and the general procedure for the calculation of the irreversibilities. We develop a computer program to solve and calculate all the exergy and mass balances. The validation of this model is done by the utilization of the data of the industrial plant. The results obtained allow us to identify the parts were the energy is mainly degraded and can be used as a guide for future improvements in the plant.
