Thermodynamic and Environmental Simulation and Analysis of Tehran Petroleum Refinery Power and Steam Plant

Oil refineries are the most energy-intensive industries and produce a lot of pollutions. So, thermodynamic simulation is important for performance analysis of equipment, estimation of emissions and environmental impacts. In this paper, simulation and thermodynamic and environmental analysis of Tehran refinery power and steam plant have been studied.

In this regards, two scenarios for performance improvement of steam and power system have been proposed for Tehran refinery. Thermodynamic simulation of each main component has been performed in Matlab Environment. To verification of simulation results, Thermoflex and Star software have been employed. Also, Sima Pro software has been used for estimation of environmental impacts based on Life Cycle Assessment (LCA).

Results show the accuracy of the thermodynamic simulation is very high. The power of steam turbines has been increased by 8.87 % in the second and third scenarios. Also, the environmental impacts have been reduced 16 % in second and 60% in third scenarios.

According to the proposed scenarios and optimization of Tehran Refinery steam network, the efficiency of the network increases energy consumption and production of pollutants is significantly reduced.
