VARNERO, María T; CARU, Margarita; GALLEGUILLOS, Karina  y  ACHONDO, Patricio. Available Technologies for Purification of Biogas used in Power Generation. Inf. tecnol. [online]. 2012, vol.23, n.2, pp. 31-40. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000200005.

Available technologies that have been implemented for biogas purification for its use in power generation are summarized and analyzed. It is known that biogas may contain some impurities and trace elements that must be removed before its use as energy source. Traditional technologies for biogas purification are based primarily on the use of physical and chemical methods, which, besides generating secondary pollutants, often have a high cost. As an alternative, biogas purification through biological processes using microorganisms has become attractive. The microorganisms can remove substances considered pollutants; especially they can remove hydrogen sulfide. It is concluded that the method is cost effective with low energy inputs and harmless to the environment and human health.

Palabras clave : purification; bioprocessing; biogas; biomethane; biofilters.
