Title (EN) PROCESS FOR RECOVERING 3-METHYLBUT-3-EN-1-OL
(FR) PROCÉDÉ POUR LA RÉCUPÉRATION DE 3-MÉTHYLBUT-3-EN-1-OL
Abstract:
(EN) The present invention relates to a process for recovering 3-methylbut-3-en-1 -ol from a feed stream F1 comprising 3-methylbut-3-en-1 -ol, one or more solvents, water, and isobutene, wherein 3-methylbut-3-en-1 -ol, the one or more solvents and water are separated from isobutene by distillation, the process comprising subjecting the feed stream F1 to distillation conditions in a distillation unit, obtaining a bottoms stream B1 which is enriched in -methylbut-3-en-1 -ol, in the one or more solvents and in water compared to the feed stream F1 subjec The present invention relates to a process for recovering 3-methylbut-3-en-1 -ol from a feed stream F1 comprising 3-methylbut-3-en-1 -ol, one or more solvents, water, and isobutene, wherein 3-methylbut-3-en-1 -ol, the one or more solvents and water are separated from isobutene by distillation, the process comprising subjecting the feed stream F1 to distillation conditions in a distillation unit, obtaining a bottoms stream B1 which is enriched in -methylbut-3-en-1 - ol, in the one or more solvents and in water compared to the feed stream F1 subjected to distillation conditions, and a top stream T1 which is enriched in isobutene, further subjecting the bottoms stream B1 to distillation conditions in a second distillation unit and obtaining a bottoms stream B2 which is enriched in 3-methylbut-3-en-1-ol compared to the bottoms stream B1 and a top stream T2 which is enriched in water compared to the bottoms stream B1, further subjecting the bottoms stream B2 to distillation conditions in a third distillation unit and obtaining a top stream T3 which is enriched in 3-methylbut-3-en-1-ol compared to the bottoms stream B2 and a bottoms stream B3. ted to distillation conditions, and a top stream T1 which is enriched in isobutene, further subjecting the bot- toms stream B1 to distillation conditions in a second distillation unit and obtaining a bottoms stream B2 which is enriched in 3-methylbut-3-en-1-ol compared to the bottoms stream B1 and a top stream T2 which is enriched in water compared to the bottoms stream B1, further subjecting the bottoms stream B2 to distillation conditions in a third distillation unit and obtaining a top stream T3 which is enriched in 3-methylbut-3-en-1-ol compared to the bottoms stream B2 and a bottoms stream B3.
(FR) La présente invention concerne un procédé de récupération de 3-méthylbut-3-en-1-ol à partir d'un flux d'alimentation F1 comprenant du 3-méthylbut-3-en-1-ol, un ou plusieurs solvants, de l'eau et de l'isobutène, le 3-méthylbut-3-en-1-ol, un ou plusieurs solvants et l'eau étant séparés de l'isobutène par distillation, le procédé comprenant les étapes consistant à : soumettre le flux d'alimentation F1 à des conditions de distillation dans une unité de distillation, obtenir un flux de fond B1 enrichi en -méthylbut-3-en-1-ol, dans un ou plusieurs solvants et dans l'eau par rapport au flux d'alimentation F1 soumis à des conditions de distillation, et un flux supérieur T1 enrichi en isobutène, soumettre ensuite le flux de fond B1 à des conditions de distillation dans une seconde unité de distillation et obtenir un flux de fond B2 enrichi en 3-méthylbut-3-en-1-ol par comparaison au flux de fond B1 et un flux supérieur T2 enrichi en eau par rapport au flux de fond B1, soumettre ensuite le flux de fond B2 à des conditions de distillation dans une troisième unité de distillation et obtenir un flux supérieur T3 enrichi en 3-méthylbut-3-en-1-ol par comparaison au flux de fond B2 et un flux de fond B3.
