Abstract :In this paper application of exergy analysis to the reactive distillation system of a Methyl TerButyl Ether insert ignore into journalissuearticles values(MTBE); production unit of a crude oil refinery is presented. In a refinery, the MTBE is obtained from methanol, and butanes insert ignore into journalissuearticles values(isobutylenes); produced in the fluidized catalytic cracking insert ignore into journalissuearticles values(FCC); unit. The reactives insert ignore into journalissuearticles values(isobutylenes); after purification are introduced to the main reaction system, the products of which are sent to the reactive distillation system to complete the reaction. A top rectification section, a bottom stripping section and a medium reaction section, compose the reactive column. The results of the exergy analysis of the unit indicate that the main exergy losses insert ignore into journalissuearticles values(about 63%); of the MTBE plant occur in the reactive distillation system, particularly in the distillation column itself and in its associated condenser. A detailed exergy analysis of the system, is presented in this paper. This paper was presented at the ECOS`00 Conference in Enschede, July 5-7, 2000
