Valoración energética de briquetas obtenidas de residuos agroindustriales mediante gasificación

Abstract

Today, the demand for energy is evident in many aspects. There is an increasing lack of resources to obtain energy, and high energy consumption represents a future problem. For this reason, the objective is to achieve alternatives that mitigate the need to use up natural sources. The objective of this research is the implementation of agro-industrial wastes as alternative sources of energy, by analyzing the energy valuation they can provide and the quality of gas available in the biomass. The methodology used had a quantitative and qualitative approach, using a randomized experimental design to explore relationships between variables and their direct relationship with the process. The study was carried out through a gasification process, where the biomass as agro-industrial waste goes through an ignition stage with a gasifying agent such as air. The result of this process is a gas that can be adequately used in industry or daily life, replacing other gases with limited sources. By means of this methodology, it was possible to determine the energetic valuation of barley bagasse, a residue commonly obtained from beer brewing. The quality of the gas that can be obtained from this biomass was also determined, being analyzed by the percentage of content of important compounds such as methane, which was found to be 0.77%, compared to nitrogen which was obtained in 64.86% being the composition of the lowest and highest respectively. It is concluded that the use of biomasses as a source of energy in industrial activities is viable. However, as an alternative source of gas, barley bagasse presents a low methane content compared to other biomasses, although it has value in terms of heat capacity, being this of 3215.21KJ/m3, considering for suitable applications.
