Thermodynamic analysis of flue gas desulphurization system

From past to present, with the increase of industrialization, sulfur dioxide emission has increased and due to increase sulfur dioxide desulfurization desulfurization systems have been developed. One of them, wet lime flue gas desulphurisation system, is used to prevent the release of sulfur dioxide in high amount. In this academic thesis, the wet lime flue gas desulphurisation system (WLFGD) is considered and the wet flue gas desulphurisation system applied in a factory where the refractory brick production is made in Kütahya province is evaluated from the termodynamic and economic point of view. The system is evaluated by energy , exergy analysis methots and thermodynamic evaluations (LCC) together with net present value (NPV) methots to determine whether the system is worth investment. As a result of the work done ,the energy efficency of the system is calculated as %48 exergy efficency of system is calculated as %59,5. Under the current working conditions, the system life has been accepted for 20 years and the investment value of the system which is found as NPV 2.999.727 TL has been determined. Due to the improvements ,the NPV value can be increased to 58.171.167 TL. Keywords: Energy-Exergy Analysis, Analysis, Net Present Value, Wet Flue Gas Desulphurization.
