Abstract

Procedimiento para la separación de mezclas de hidrocarburos conteniendo etileno por rectificación a bajas temperaturas, en que la mezcla conteniendo el etileno se separa en una fracción líquida de sumidero y una fracción gaseosa de cabeza, se calienta la fracción de cabeza, se comprime y se licua parcialmente en intercambio térmico con la fracción de sumidero, que se calienta en ello, se expansiona y, como reflujo, se aporta de nuevo a la rectificación y se extrae parcialmente como etileno de producto, caracterizado porque el calor necesario para el calentamiento del sumidero se aporta parcialmente por un circuito de frío cerrado.
