Post-pandemic Long-term Energy Demand Forecasting Using Leap Software in the Páramo De Santurbán: the Case of Pamplona North De Santander

Three different forecast scenarios (from 2018 to 2040) were simulated in the Long-Range Alternative Energy Planning model. The first scenario was calling usual trend, considered average growth rate of historical demand data. The second scenario was energy efficiency based on the energy intensity indicator agreed upon in the Program for the Rational and Efficient Use of Energy, which is a public policy guideline to promote the best use of energy resources (electric stoves, use of panels photovoltaics and other energy sources). Finally, the third scenario was post-COVID-19 trending, which was based on economic activity degree of openness of 82 %, at the end of 2020 and 100 % openness was reached in the fourth quarter of 2021. This COVID-19 projection was carried out in the absence of similar preceding events, which were accompanied by a statistical history. The results obtained in growth forecasts are the same as those that were incorporated in the energy demand projection in the national energy plan to 2050. Estimations from each of these scenarios were compared using data from a survey realized in Pamplona. The results of this study suggest a growth close to the national average. However, energy fuel mix will change, such that electricity will be the most highly consumed energy form followed by LPG, natural gas, and wood.

The present study presents the analysis of the phenomenology of dispersion of a hydrocarbon in a body of fresh water, using as basis the mathematical modeling presented in the literature. The growth of the stain is studied from experimental tests established by a design of experiments to a determined time. The established criterion was developed for a controlled environment based on the model of dispersion of Fay, comparing the results of the model with the experimental data.

El problema con esta materia prima es que contiene grandes cantidades de ácidos libres que reaccionan con el catalizador alcalino para formar jabones. Para evitar la formación de jabones, se requiere un pretratamiento de la materia prima con catalizadores ácidos. La reacción de transesterificación se completa con un catalizador alcalino. La mayor producción de biodiesel, corresponde al oleato de metilo, con un 4.985 kmol/hr, y para el butirato de metilo se obtiene una producción de 4.658 kmol/hr.

The Technologies as steam reforming, selective oxidation, membrane reforming and thermal plasma are described. An analysis of the possibility of conversion of methane from anaerobic reactors and sanitary landfills into liquid hydrocarbon is done.
