Nueva herramienta para la operación económica  en una planta de desulfuración húmeda de  los gases de combustión

Authors

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.
