Abstract

Una lechada de absorción de óxido de nitrógeno y su preparación, y el método de uso para la extracción de óxido nítrico en corrientes de gas, que pertenecen al campo técnico del control de la contaminación atmosférica y la protección ambiental relacionada, que se caracteriza porque la lechada de absorción contiene al menos un compuesto de cloruro férrico anhidro, monohidrato de cloruro férrico, dihidrato de cloruro férrico y un complejo de cloruro férrico y cloruro de hidrógeno. La lechada de absorción reacciona con el óxido nítrico de la corriente de gas, para que la lechada absorba el óxido nítrico de la corriente de gas, con lo que logra la purificación del gas. Después de la regeneración, el absorbente se puede reciclar.
