Abstract

Procedimiento de limpieza de las paredes internas de reactores químicos, utilizados en la obtención de diversos productos que aparecen durante la fluoración, con el fin de conservar las paredes en un estado próximo de sus características principales iniciales, estando constituidas estas características por el mantenimiento de las paredes internas a una temperatura soportable sin daño para el reactor, y por ausencia de depósito de fase parásita que tendría una incidencia nefasta en los coeficientes de intercambio térmico, caracterizado porque se deposita sobre las paredes internas un agente protector renovable constituido por un derivado del flúor.
