요약서:
(EN) The present invention relates generally to olefin polymerization. In particular, the present relates to a process for the separation of a hydrocarbon-containing feed stream (20) comprising the steps of: (a) optionally cooling said hydrocarbon-containing feed stream (20) using an absorption refrigeration cycle (37), (b) introducing said feed stream (20) into a first distillation zone (22) for subjecting said feed (20) to distillation conditions adapted to remove b1) a bottom stream (25) comprising co-monomer, and b2) an overhead stream (29) comprising hydrocarbon diluent, olefin monomer and further components such as H2, N2, O2, CO, CO2, and formaldehyde, and (c) introducing the overhead stream (29) of step b) in a second distillation zone (23) for subjecting said stream (29) to distillation conditions adapted to remove c1) a bottom stream (30) comprising substantially olefin-free hydrocarbon diluent, c2) a side stream (31) comprising hydrocarbon diluent, and c3) an overhead vapor stream (32) comprising olefin monomer, diluent and further components such as formaldehyde, H2, N2, O2, CO and CO2, and (d) cooling the temperature of said removed overhead vapor stream (32) using an absorption refrigeration cycle (34) prior to separating (35) said olefin monomer from said diluent in said overhead vapor stream (32). Said invention also relates to a polyolefin production process and to a polyolefin production unit.
(FR) La présente invention concerne d'une manière générale la polymérisation des oléfines. En particulier, la présente invention porte sur un procédé pour la séparation d'un courant d'alimentation à teneur en hydrocarbure (20) consistant: (a) facultativement, à refroidir ledit courant d'alimentation à teneur en hydrocarbure (20) à l'aide d'un cycle de réfrigération par absorption (37), (b) à introduire ledit courant d'alimentation (20) dans une première zone de distillation (22) pour soumettre ladite alimentation (20) à des conditions de distillation adaptées pour éliminer, b1) un courant de résidu de distillation (25) comprenant un comonomère, et b2) un courant de distillat de tête (29) comprenant un diluant hydrocarboné, un monomère oléfinique et d'autres composants tels que H2, N2, O2, CO, CO2 et du formaldéhyde, et (c) à introduire le courant de distillat de tête (29) de l'étape b) dans une seconde zone de distillation (23) pour soumettre ledit courant (29) à des conditions de distillation adaptées pour éliminer, c1) un courant de résidu de distillation (30) comprenant un diluant hydrocarboné sensiblement exempt d'oléfine, c2) un courant latéral (31) comprenant un diluant hydrocarboné, et c3) un courant de vapeur de distillat de tête (32) comprenant un monomère oléfinique, un diluant et autres composants tels que le formaldéhyde, H2, N2, O2, CO et CO2, et (d) refroidir la température dudit courant de vapeur de distillat de tête retiré (32) à l'aide d'un cycle de réfrigération par adsorption (34) avant la séparation (35) dudit monomère oléfinique à partir dudit diluant dans ledit courant de vapeur de distillat de tête (32). L'invention porte également sur un procédé de production de polyoléfine et sur une unité de production de polyoléfine.
