CACUA-MADERO, Karen Paola  y  HERRERA-MUNERA, Bernardo Argemiro. Revision of Combustion with oxygen-enriched air as a strategy to increase energy efficiency. Ing. Univ. [online]. 2013, vol.17, n.2, pp.463-482. ISSN 0123-2126.

Among the available alternatives for increasing the energy efficiency in combustion processes there is the combustion with oxygen-enriched air, which consists in increasing the concentration of oxygen in the atmospheric air to reach levels of up to 100%. This study is a review of the phenomenology of the combustion process with enriched air, with emphasis on thermodynamic aspects, chemical and kinetic. Likewise, we present the methods for obtaining the oxygen enriched air more applied so far, such as the oscillating pressure adsorption in molecular sieves and cryogenic distillation, and those that are in a state of development, such as the separation membranes. Finally, we review the most common applications of combustion with enriched air, such as high-temperature industrial processes, CO2 capture and sequestration, and internal combustion engines, as well as research advances on this issue in Colombia.

Palabras clave : Combustion with enriched air; energy efficiency; high temperature membranes.
