Abstract

Procedimiento para la purificación de gases de escape provenientes de un reactor de melamina de alta presión con formación de productos precursores de la melamina, donde en una primera etapa se ponen en contacto los gases de escape con una urea fundida circulante que contiene productos precursores de la melamina y NH3 y en una segunda etapa, con urea fundida fresca.
