Abstract
In the present study, exhaust gases from Tehran refinery crude oil furnace are used
in a Heat Recovery Steam Generator (HRSG)for generating steam. Then, the steam is directed
to a double effect absorption refrigeration cycle to produce cooling. To meet the object, mass
and energy balance equations of the coupling is carried out for both the HRSG and the
absorption chiller and unknown thermodynamic parameters of the system are evaluated.
Afterward, by conducting exergy analysis and using the thermoeconomic method, the cost of
the product (refrigeration here) is calculated. Finally, optimization is accomplished
simultaneously on both HRSG and absorption chiller in order to minimize the cooling cost by
the means of a Genetic algorithm. The outcomes indicate that by using the optimized
integrated system 5627 tons of refrigeration is obtainable at the price of 0.0104 (USD per
second). Since the flue gas was wasting to environment pricelessly, it should be noted that by
implementing the proposed coupling 1.186×107cubic meter of natural gas with the price of
1.508×106(USD) will be saved annually.
