چکیده:

Steam network of petroleum refinery is energy intensive, and consequently contribute significantly to the greenhouse gases emissions. A simple model for the estimation of CO2 emissions associated with operation of steam network as encountered in refineries is introduced. In conjunction with a shortcut model this model has been used to calculate of the steam network of an existing refinery aiming at minimization total annualized cost with considering emissions. The view of optimization in this study is CO2 emission. In this paper, the case study is steam network of southern Tehran refinery. Simulation of steam network of Terhan refinery is performed in STAR software that licensed by K.N. Toosi University of Technology. Mathematical linear programming method is applied to optimization of steam network. In addition, the short cut model of CO2 production is provided for evaluation of steam network with considering CO2 production taxes and other economic effects in total annualized cost. Result is shown that total annualized operating cost (TAOC) is reduced about 1.524% without considering CO2 tax. However, 14.027 % of TAOC decreases when we considering CO2 tax.
