This video explains how biogas is produced at a bioconstruct facility. Biomass, like maize, is processed to create methane gas. This gas can then be used to generate electricity or thermal energy. The raw materials used in biogas installations are known as substrates - such as straw, agricultural products, and industrial wastes.

• 00:00:00 This video explains how biogas is produced in a bioconstruct facility, with biomass such as maize being processed to produce methane gas. This gas can then be used for electricity or thermal production, with the raw materials used in biogas installations known as substrates - such as straw, agricultural products, and industrial wastes. In the following video, one of the substrates being used in this biogas facility, straw, is explained. Straw is stored temporarily in stables before being bombarded with a loader at high speed to break it down into small pieces. The maize falls from the loader into a mixing tank equipped with two rotating paddles that quickly mix solid materials before fermentation begins. The gas produced in this facility is green and composed of approximately 50-70% methane. Once the fermenters are filled with fresh biomass, they are closed hermetically, heated, and the substrates are replaced every few days. Within a few weeks, the biogas desired will be produced, and the gas will slowly rise to the top of the tanks where it is collected and vented. The biogas is then transferred to two storage tanks before being distributed to agricultural fields.
• 00:05:00 The video explains how biogas is produced from organic matter using water, carbon dioxide, and a sulfurous acid. The gas is then extracted from the water vapor and acid. After the gas has been created, the water vapor is released in blue color and collected. The sulfurous acid is then neutralized in a biological plant of desulfurization with the help of air introduced. After the bacteria have grown on the chains of these deposit, the sulfurous acid is decomposed into sulfur and harmless water. The biogás thus practically without pressure is transported to a compressor to obtain the necessary pressure for the subsequent combustion to condense the water vapor and release the biogas of suspended substances and silicates. The biogás is washed and dried with cold water fog to a temperature below 5 degrees Celsius to check automatically the treatment of the gas. The gas is analyzed continuously for the presence of methane gas and acetic acid sulfhídrico dióxido of carbono and oxygen of the biogás by an online measurement. This guarantees high efficiency and reliability of biogas operation in case of an overproduction of biogas. It is necessary to use a flare for the methane release to the atmosphere without burning because this is harmful
