Abstract
La presente invención se refiere a un procedimiento para reducir al mínimo la corrosión debida a la humedad en los gases de descarga procedentes de un reactor de cloración directa a alta temperatura ("HTDC"), para convertir el etileno al 1,2-dicloroetano o dicloruro de etileno ("EDC"), estos gases de descarga se recirculan a un reactor de oxicloración, también para la producción de EDC, dicho procedimiento comprende: a) reaccionar el cloro húmedo, que tiene un contenido de humedad en el margen de 100 ppm a alrededor del 1 por ciento en peso de la carga de cloro, con una cantidad en exceso de la estequiometrica del etileno, en un medio líquido de hidrocarburos clorados, a una temperatura de al menos unos 50 grados C, a la presión atmosferica o mayor, para proporcionar un EDC producto en una carga retirada desde el reactor HTDC; b) separar el EDC producto de los componentes de punto de ebullición mayor en dicha carga retirada del HTDC, en un elemento separador de vapor-líquido; c) condensar la parte superior procedente del elemento separador en un tambor superior, para así condensar la porción principal del EDC, y descargar una corriente que consta esencialmente de nitrógeno, etileno, cloro, HC1 y menor del 1.5 por ciento en peso de agua, con base en el peso de la corriente de descarga; d) enfriar la corriente de descarga a una temperatura en el margen de -30 a 0 grados C, para condensar los productos condensables en la corriente de descarga y el agua de congelación; e) separar el agua y los productos condensables de aquellos no condensables, que incluyen el nitrógeno, cloro, etileno y HC1, sin obturar las líneas con hielo; y f) recircular los productos no condensables, esencialmente exentos de agua, al reactor de oxicloración, por lo cual se reduce al mínimo la corrosión debida a la presencia de agua en la línea de recirculación y el equipo.
