| Sumario: | The research aimed to evaluate the removal of CO2 from biogas from the sanitary landfill in the municipality of Palmas – Tocantins. The flow measurement (weekly and daily profile) of the biogas was carried out through a vertical drain located in one of the cells of the Landfill. LPG Building gas measurement operation was carried out through the biofuel carried out from a gas meter. The biogas purification tests were carried out using a spray tower scrubber, using calcium hydroxide solutions to remove CO2. The variable concentration of the alkaline solution was evaluated during the biogas purification tests. Samples were collected and analyzed using chromatographic techniques, before and after the biofuel purification system. The biogas flow profile equal to 18 m3/day indicates the possibility of application of this biofuel as an energy resource. During the tests of transformation of biogas into biomethane, using a washing column with alkaline solution, a methane content of 75% was obtained when calcium hydroxide solution with a concentration equal to 0.16 mol/L was used, which points to obtaining a better quality biofuel after a purification system, meeting the characteristics recommended by the National Petroleum Agency (ANP), for industrial application purposes. |
