In recent years a big effort is aimed at the study of technology for carbon dioxide reduction in flue gas but actual technologies imply the costly step of CO 2 separation.

In this paper it is examined whether the reaction between RDF and fluegas, supported by the solar energy is attractive from an economic point of view. First of all, the advantage of using RDF in this remediation instead of its use as a raw-material in gasification is examined. The use of RDF in the remediation of the fluegas is advantageous if it is considered the annual production of RDF in agglomerates containing less than 500000 inhabitants.

The carbon tax increases its importance as much as it increases as the content of CO 2 in the fluegas. The influence of the other parameters is rather independent of the ratio between carbon dioxide and steam in the fluegas while it is more pronounced the variation of the energy cost as a function of the investment if the plant size is reduced.

Abstract
In recent years a big effort is aimed at the study of technology for carbon dioxide reduction in flue gas but actual technologies imply the costly step of CO 2 separation. An alternative is to convert it to an energy source by means of the Bouduard reaction. In this paper it is examined whether the reaction between RDF and fluegas, supported by the solar energy is attractive from an economic point of view. First of all, the advantage of using RDF in this remediation instead of its use as a raw-material in gasification is examined. The use of RDF in the remediation of the fluegas is advantageous if it is considered the annual production of RDF in agglomerates containing less than 500000 inhabitants. Besides, the effect of the annual production of RDF, carbon tax, manpower and investment cost is examined. The carbon tax increases its importance as much as it increases as the content of CO 2 in the fluegas. The influence of the other parameters is rather independent of the ratio between carbon dioxide and steam in the fluegas while it is more pronounced the variation of the energy cost as a function of the investment if the plant size is reduced.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
