Denitrogenation or oxyfuel combustion is ,based on separation of oxygen from nitrogen before combustion. The CO2 obtained is concentrated and easy to isolate after combustion. Oxyfuel combustion has been used in different industrial applications, although technological challenges have to be met for large scale power generation. An important area of improvement of this concept is to be found in the air separation unit, with the help of new technologies like membrane separation technologies, high temperature oxygen adsorption technologies, and improved cryogenic distillation.
