Abstract: (8 Views) |
In this research, the new multiple production system consisting of Rankine cycle, heat exchanger generator and ejector cooling system based on sulfur dioxide is evaluated from thermodynamic and economic aspects. The waste heat from the steam turbine is recovered by the steam heat exchanger generator and the required cooling load is created in the ejector cooling system. In addition, parametric analysis is done to evaluate the changes of key parameters in various working conditions on the performance of the system. With the thermodynamic analysis done on the proposed system, the energy and exergy efficiency is obtained as 20% and 26%, respectively. In the present work, updated cost functions are used in the economic analysis, so that the cost of the entire system is 233 dollars per gigajoule. In the present study, the simultaneous production system with a new arrangement is introduced, which has a favorable thermodynamic performance and is economical. |
