THE PRESENT INVENTION RELATES TO A METHOD FOR PREPARING LINEAR ALPHA-OLEFINS BY OLIGOMERISATION OF ETHYLENE, COMPRISING THE STEPS OF: (I) OLIGOMERISING ETHYLENE IN A REACTOR IN THE PRESENCE OFA SOLVENT AND A CATALYST; (I I) TRANSFERRING A LIQUID ORGANIC OUTLET STREAM OF THE REACTOR, CONTAINING SOLVENT, CATALYST, DISSOLVED ETHYLENE AND LINEAR ALPHA-OLEFINS, TO A CATALYST DEACTIVATION SECTION; (III) DEACTIVATING THE CATALYST BY WASHING THE OUTLET STREAM WITH AN AQUEOUS BASIC PHASE TO OBTAIN A DEACTIVATE CATALYST CONTAINING AQUEOUS PHASE AND A WATER SATURATED ORGANIC PHASE; (IV) SEPARATING THE AQUEOUS PHASE AND THE ORGANIC PHASE FROM STEP (III); (V) TRANSFERRING THE WATER SATURATED ORGANIC PHASE TO A DISTILLATION COLUMN; (VI) DISTILLING THE WATER SATURATED ORGANIC PHASE; AND (VII) SEPARATING THE DISTILLED ORGANIC AND AQUEOUS PHASES. |
