Abstract

Procedimiento de separación de una corriente (20) de alimentación que contiene hidrocarburos que comprende las etapas de: - a) refrigerar dicha corriente (20) de alimentación que contiene hidrocarburos usando un ciclo (37) de refrigeración por absorción antes de la destilación, - b) introducir dicha corriente (21) de alimentación refrigerada en una primera zona (22) de destilación para someter dicha alimentación (21) refrigerada a condiciones de destilación adaptadas para eliminar b1) una corriente (25) de fondo que comprende co-monómero, y b2) una corriente (29) de cabeza que comprende diluyente de hidrocarburo, monómero de olefina y componentes adicionales, tales como H2, N2, O2, CO, CO2 y formaldehido, y - c) introducir la corriente (29) de cabeza de la etapa b) en una segunda zona (23) de destilación para someter dicha corriente (29) a condiciones de destilación adaptadas para eliminar c1) una corriente (30) de fondo que comprende un diluyente de hidrocarburo sustancialmente libre de olefinas, c2) una corriente (31) lateral que comprende diluyente de hidrocarburo, y c3) una corriente (32) de vapor de cabeza que comprende monómero de olefina, diluyente y componentes adicionales, tales como formaldehído, H2, N2, O2, CO y CO2, - d) refrigerar la temperatura de dicha corriente (32) de vapor de cabeza eliminada de la etapa c3) usando un ciclo (34) de refrigeración por absorción antes de separar (35) dicho monómero de olefina de dicho diluyente en dicha corriente (32) de vapor de cabeza, y accionar dicho ciclo (34) de refrigeración por absorción de la etapa d) usando calor reciclado desde un hervidor de la primera zona (22) de destilación.
