Abstract
La invención se refiere a un método para separar una fracción rica en nitrógeno de una fracción inicial que contiene sustancialmente nitrógeno e hidrocarburos en donde la fracción inicial se condensa parcialmente y se separa por rectificación en una fracción rica en nitrógeno y una fracción rica en metano. De conformidad con la invención, durante una interrupción del suministro de la fracción inicial la(s) columna(s) (T1/T2) de separación utilizada(s) para la separación por rectificación así como los cambiadores de calor (E2) que sirven para la condensación (E1) parcial de la fracción inicial y para la refrigeración y calentamiento de las corrientes de proceso que se generan durante la separación por rectificación se mantienen mediante uno o varios refrigerantes (6-11) diferentes a niveles de temperatura que sustancialmente corresponden a los niveles de temperatura durante la operación normal de la(s) columna(s) (Tl/T2) de separación y de los cambiadores de calor (El, E2).
