Abstract
Due to the importance of energy consumption in a steam network of oil refinery as a significant unit, present study is concerned with the optimization of an oil refinery steam network. Here, the attempt was made to use concepts such as first and second thermodynamic laws, thermo-economic, environmental and economic discussions to investigate three different scenarios about Tehran refinery steam network. The first scenario was a base case in which boiler efficiency was 67%. The second scenario was the same as the first scenario, except that boilers efficiency was 86%. The third scenario was also similar to the base one. However, the difference was that one of the boilers was eliminated from the site. Instead, two gas turbines with heat recovery steam generator were introduced and the boiler efficiency was 86%. The obtained results showed that the annual cost of second and third scenarios fell to the rate of 22% and 42% respectively compared to the first scenario. To carry out thermodynamic modeling of some equipment such as steam turbines, gas turbines, and thermal recovers, Star software was utilized. In this paper, there has been an attempt to use concepts such as first and second thermodynamic laws, economic, exergoeconomic, environmental discussions in order to investigatethree different scenarios around Tehran refinery steam network. Finally, the annual cost of second and third scenarios has fallen down to the rate of 22% and 42% respectively compared to the first scenario. In order to carry out thermodynamic modelling of some equipment such as steam turbines, gas turbines and thermal recovers, Star software was utilized.
