ABSTRACT:
Large coal combustion plants must ensure that their emissions comply with the emission limit values set by the prevailing legislation. In this paper, we study flue gas desulphurisation at the Puente Nuevo Power Plant (330 MW, Spain). The objective is to optimise energy and reagent consumption. The results were obtained at industrial scale using the following variables: pH, liquid absorbent flow, flue gas flow, residence time in the absorber, and energy consumption associated with the process developing a new tool for use as an operation protocol that allows to economize the process in wet flue gas desulphurization plants of optimum and safety form. The study was carried out taking into account compliance with the current emission limit values established under Spain's National Emission Reduction Plan for Large Combustion Plants and with a view to stricter legislation in the future.
