Abstract

Se describe un proceso termo-químico para desparafinación de ductos conductores de hidrocarburos, con ductos que tiene gran extensión y diámetrointerno, es decir, grandes dimensiones, mediante el uso de un sistema generador de nitrógeno/emulsión preparado y bombeado desde la plataforma de produccióndirectamente hacia el ducto parafinado o de modo circulante a través de una línea auxiliar, en el cual se retrasa el comienzo de la reacción de generaciónde nitrógeno y calor según las necesidades operacionales por el anadido de un activador polianhidrido adípico de hidrodegradabilidad controlada.
