Abstract

This volume presents an integrated assessment of the performance of energy conversion systems based on ligno-cellulosic biomass by referring to the nominal efficiency of each element as well as to the global performance of the integrated set. On the one hand, it focuses on the conversion of biomass into energy, on the other hand, on the distribution of heat to the end users. These two aspects are complementary and an integrated analysis is essential to design high-efficiency systems from a global perspective.The first part of the study defines the current energy performance achievable in practical applications on the basis of detailed energy monitoring of both combustion and gasification plants. The second part focuses on the energy and economic assessment of the distribution and use of the heat generated by a plant.

Keywords

Biocombustible: Residuos del plátano

Potencialidad de los residuos del plátano para su uso como biocombustible.

Investigadores de la Universidad Politécnica de Madrid (UPM) pertenecientes al grupo de Agroenergética han llevado a cabo un estudio para evaluar el potencial de la biomasa residual del plátano producido en la provincia de El Oro, en Ecuador, para aplicaciones de bioenergía.

Los resultados de este estudio indican que con la utilización de este tipo de residuos se podría cubrir el 55% de la demanda eléctrica de la provincia y el 10% de la demanda de bioetanol de todo el país.
El plátano es uno de los cultivos más importantes en el mundo. En el año 2013 se produjeron 106 millones de toneladas y la mayoría de la producción se concentró en dos continentes, Asia (57%) y América (26%), pero se le conoce y consume a nivel mundial por su disponibilidad a lo largo de todo el año.

Methods

In this work, the potential of banana residual biomass produced in the province of El Oro, Ecuador for bioenergy applications was assessed using Geographic Information Systems—GIS. The methodology included the assessment of biomass distribution, facility location, transport optimization and a novel virtual land parcel that allows for these kinds of studies in areas with lack of geo-referenced information.

Results

According to our approach, El Oro province has an available biomass potential of 190,102 t fm year−1 of starchy residual biomass and 198,602 t dm year−1 of lignocellulosic residual biomass. Two candidate points located at 79°51′12″W3°11′21″S and 79°52′49″W3°17′49″S were identified for the installment of energy conversion facilities supplied with residual biomass.

Conclusions

From the available potential of starchy biomass it would be possible to obtain up to 19 million liters of bioethanol per year assuming an average yield of 101.2 l t−1 fresh matter; while the available lignocellulosic biomass, which energy content (Lower Heating Value, moisture free biomass) was determined at 12.9 MJ kg−1 on average, could be used for power generation with an installed capacity of 18 MW. Chemical characterization of the lignocellulosic biomass suggested that further studies should be undertaken regarding the potential application of these crop residues to second generation bioethanol.
