Abstract: 
Crude distillation unit is one of the most energy consumption units in a refinery that its optimization will directly affect both refinery performance and products qualities. Exergy analysis can define waste and insufficient points of a system by using 1st and 2ndthermodynamic laws. In this study, crude distillation unit of Tabriz refinery was simulated by Aspen Plus software and through exergy analysis indicated that the atmospheric distillation column section, and also LPG-Naphtha splitter section owned the lowest exergy efficiencies. Also it has been resulted that the main column has the largest value of exergy improvement potential. Hence, in this work, some solutions were suggested for increasing exergy efficiency that include introducing the preflash vapour directly to the main column, decreasing pressure drop of furnace and preflash drum, increasing the pump-arounds rates and changing their return stages to the main column. Moreover, this investigation evaluates their effects on energy loss and fuel gas rates reduction of the furnaces. Regarding the achieved improvements through the offered changes, it has been observed 1.6% increase and 2.03% reduction as maximum rates, and 0.1% rise and 0.65% drop as minimum rates, in exergy efficiency and fuel gas consumption respectively, according to base case. Also, the best proposed modification was considering the solutions of 15% rise in crude distillation column pump-around rates with an increase in the column’s feed temperature and also with a decrease in the condenser’s duty that caused the most reduction rate in energy loss about 3.22% for the unit.
