| description | The use of biogas generated in landfills has gained importance in developing countries like Colombia. Taking into account that this biogas presents poor combustion properties that make interchangeability with other combustible gases difficult, the elimination of gases and vapors, such as CO2 and H2O, through a cleaning process, in which the biogas is converted to biomethane, improves the biogas properties as a fuel gas for general use. In this work, we simulated the generation of biogas at El Carrasco sanitary landfill in Bucaramanga, using the US EPA (United States Environmental Protection Agency) landfill gas emissions model. Additionally, we simulated the biogas cleaning process to extract the remaining moisture using the ProMax software; for this, we used three different amines (MDEA, MEA, and DEA), followed by a glycol dehydration process. The results showed that the amine MEA produced the largest increase in the concentration of CH4 (90.37 %) for the biogas generated in the landfill. Furthermore, dehydration with glycol was an efficient process to obtain a gas with a high percentage of methane (91.47 %) and low water presence (1.27 %); this would allow the use of biomethane in conventional industrial combustion processes and power generation. |

La utilización del biogás producido en vertederos de basura ha ganado importancia en países en vía de desarrollo, como Colombia. Teniendo en cuenta que este biogás tiene propiedades pobres de combustión que dificultan el intercambio con otros combustibles, la eliminación de gases y vapores, como el CO2 y el H2O, por medio de procesos de purificación en los que el biogás es convertido a biometano, mejora las propiedades del biogás como combustible para uso general. En este trabajo se simuló la producción de biogás en el vertedero de basura El Carrasco (Bucaramanga), usando el modelo de emisiones de gases en vertederos de la US EPA (United States Environmental Protection Agency). Adicionalmente, se simuló el proceso de purificación del biogás utilizando el software ProMax; el objetivo de este proceso es extraer la humedad del biogás, para lo cual se utilizaron tres aminas diferentes (MDEA, MEA y DEA) y un proceso posterior de deshidratación con glicol. Los resultados mostraron que la purificación con amina MEA logró producir el mayor incremento en la concentración de CH4 (90.37 %) en el biogás generado en el vertedero. Además, la deshidratación con glicol fue un proceso eficiente para obtener gas con un alto porcentaje de metano (91.47 %) y un bajo porcentaje de agua (1.27 %); estos resultados sugieren que el biometano se podría usar en procesos industriales convencionales y en generación de energía.
