In the last decade, there has been a notable increase in the world production of synthesis gas from biomass gasification; this process constitutes a way for energy utilization from the thermochemical conversion of forest residues. The objective was to carry out an energy analysis using a residual forest biomass gasification system at the Las Terrazas eco-tourist complex in order to obtain useful energy. A model was developed in the SuperPro Designer software for the gasification of this type of biomass resource, which allows for predicting the evolution of the composition of the lean gas as a function of temperature and the elemental composition of the forest biomass. For the gas produced by gasification, a calorific value of 5.87 MJ/m3 is obtained. In the power block, consisting of a gas turbine with a coupled electric generator, electricity generation is achieved with a capacity to generate. With the waste heat from the turbine's exhaust gases, it is proposed to generate 0.5 kg/s as steam for cooking food and for the sanitary water system of various service facilities of the eco-tourist complex.

In this work, an estimation was made of the potential for energy generation with biomass resources from the area, and a system of sustainability indicators was proposed to evaluate the contribution of the use of biomass resources to the eco-tourism complex Las Terrazas. It was confirmed that the most important biomass wastes are from pigs, which produce 3 m3 biogas/day, and forestry wastes from the mountains. In a total of 5 201 ha with forest resources, a residual biomass potential of 4 524,87 t/year was estimated, which corresponds to a usable energy potential of 9,52 GWh/year. A system of biophysical indicators was proposed that can express the level of sustainability that the settlement could reach from the best use of the available biomass resources.

The objective of this work was to select the required equipment among the set of available, to satisfy the energy demand of a territory, optimizing a commitment between investment and operation costs and polluting to the atmosphere emissions. For the solution of the problem, a decomposition scheme that include a multiple criteria linear programming task, at the higher level, and integer programming optimization subtasks at the lower level is applied. For solving the last ones an algorithm of the Integration of Variables methods applied. These tasks are solved using the real data from the municipality of Ganda, Benguela, Angola, determining the basic facilities, among the available, that should be acquired and in the areas of the territory where each installation should be installed. It was demonstrated that the problem of optimal selection of energy equipment in isolated regions can be solved by the methods used. [ABSTRACT FROM AUTHOR]
