Abstract

La présente invention concerne un traitement de récupération d'éthylène à partir d'un flux de produit de polymérisation d'un système de production de polyéthylène faisant appel à la séparation d'un flux de gaz léger du flux de produit de polymérisation, le flux de gaz léger comprenant de l'éthane et de l'éthylène n'ayant pas réagi, à la mise en contact du flux de gaz léger avec un système de solvant d'absorption, la mise en contact du flux de gaz léger avec le système de solvant d'absorption se faisant à une température comprise dans la plage d'environ 40 °F à environ 110 °F, au moins une partie de l'éthylène n'ayant pas réagi issu du flux de gaz léger étant absorbé par le système de solvant d'absorption, et à la récupération de l'éthylène n'ayant pas réagi à partir du système de solvant d'absorption pour obtenir de l'éthylène récupéré.
