ORTEGA VIERA, Lianys; RODRIGUEZ MUNOZ, Susana; FERNANDEZ SANTANA, Elina y BARCENAS PEREZ, Liuver. Principal methods for biogas desulphurizatio. RIHA [online]. 2015, vol.36, n.1, pp. 45-56. ISSN 1680-0338.
At present the world is facing an energy crisis, where one of the factors contributing to it is the indiscriminate use of conventional fuels, therefore, alternatives for obtaining biofuels such as biogas are being sought. Biogas contains hydrogen sulphide, which has a high toxicity and corrosive properties, which limits their use. Methods for efluent gas desulphurization can be classified according to their physico-chemical principles as follows: absorption using inorganic and organic chemicals, physical adsorption, biotecnologichal methods and membrane filtration. In this paper an analysis of the methods used worldwide is presented as well as the results achieved from the Cuban experience.
