SUMMARY:

 Greenhouse gases emissions and their consequences are one of the main environmental problems faced today. To mitigate the impacts caused by this phenomenon, Brazil seeks to reduce CO2 emissions by 43% by 2030 in order to meet the Paris Agreement. To achieve this goal, it is possible to use techniques based on the principle of Carbon Capture and Storage, with Chemical Looping Combustion being one of these technologies. These processes are versatile in terms of the use of fuels in the three states of matter. As the growing depreciation of glycerin in recent years, there is a need to relocate this by-product to other applications that could increase its market value, since this waste product represents about 10% of the amount of biodiesel generated. Thus, this proposal aims to evaluate the feasibility of glycerin on Chemical Looping Combustion and provide its mathematical modeling. The crude glycerin solution will be synthesized considering water, methanol and ethanol as the main contaminants. The experiments will be carried in two sets: the first to determine the best operational conditions (oxygen-to-fuel molar ratio, H2O/C3H8O3 molar ratio and TRR) and afterwards another set of experiments will be done for the contaminants using the best operational conditions determined by the previous set. The gases generated after the combustion will be analyzed by analyzers to determine the volumetric composition of the outlet flow. A simulação do processo de Combustão por Recirculação Química será desenvolvida no Aspen Plus® em três etapas: reprodução de simulação previamente existente para combustíveis gasosos, validação da estratégia reproduzida com dados experimentais de etanol e simulação do processo para a glicerina. The Chemical Looping Combustion simulation will be developed on Aspen Plus® in three stages: implementation of a simulation previously reported for gaseous fuels, validation of the strategy developed in the first stage using experimental data of ethanol as fuel and process simulation using glycerin.
