✦ Synopsis

This paper presents a new approach for the exergy analysis of chemical reactors. It consists in the formulation of a new thermodynamic performance criterion which takes into aecount the useful exergy produced and the exergy expended to accomplish the reactor intended function. The implementation of the method is illustrated in the case of the catalytic oxidization of sulphur dioxide in a fIow reversal reactor. The response pattern of the exergy effkiency coefkient to changes in some design and operating parameters is used to identify dominant effects and beneficial modifications to the reactor.
