Biovin: Indústria brasileira de biometano

Abstract

The present work aims to present Biovin: Brazilian biomethane Industry, which aims to establish itself in the market as a power plant for the production of electricity from biogas generated by the anaerobic digestion of vinasse, a byproduct resulting from ethanol production through sugarcane. Through a market analysis, it was found that there is an environmental disadvantage related to the disposal and treatment of vinasse, and based on this context, Biovin will play a crucial role in solving this problem. The plant will be strategically located in Ribeirão Preto, in the interior of São Paulo, due to the large concentration of ethanol production plants. In terms of the process, a UASB reactor was chosen to perform anaerobic digestion, and the implementation of a gas storage system in a gasometer, after biomethane purification using activated carbon filters and membranes, will ensure the production of a high-efficiency and stable product. Biovin will operate for 335 days per year, producing 50.16 million m³ of biomethane, in addition to providing sustainable energy, Biovin will also produce biofertilizers and CO2 as byproducts of the biomethane production process, generating 117912 cubic meters of biofertilizer and 7319,67 cubic meters of CO2 annually. By executing the project in a practical and advantageous manner, without harmful residues, Biovin demonstrates a commitment to environmental preservation by integrating the production of clean and renewable energy with the treatment of industrial waste, also producing value-added byproducts. Therefore, considering the new environmental challenges and the need for more sustainable energy sources, Biovin will position itself as a major company in the biomethane production sector, contributing to the socioeconomic development of the country and the preservation of the environment.
