Abstract
Procedimiento para la destilación de óxido de etileno a partir de una mezcla que contiene óxido de etileno, en una columna a una presión absoluta de 2 hasta 10 bares y una temperatura de 20 hasta 180 C, retirándose óxido de etileno puro, en estado de agregación líquido o gaseoso, a través de la cabeza o a través de una salida lateral en la zona de concentración de la columna, caracterizado porque se conduce la mezcla a través de varias zonas, dispuestas sucesivamente, con empaquetaduras de chapas metálicas estructuradas o con cargas a granel de cuerpos de relleno, que se encuentran en el interior de la columna y una de las cuales al menos está en comunicación con un sistema de extinción, mediante el cual se conduce a través de la o de las zonas un agente de extinción líquido, miscible con el óxido de etileno, por la parte externa de la columna, tan pronto como la presión en la columna sobrepase un valor límite.
