    Abstract: The present invention relates to a process for the oligomerization of ethylene , comprising the steps of: a) oligomerizing of ethylene in a reactor in the presence of solvent and catalyst; b) transferring reactor overhead effluent to an externally located cooling device and recycling condensed effluent into the reactor; c) transferring the reactor bottom effluent to a series of fractionation columns and , in the following order, i) optionally separating C6 fraction , ii) separating C6 fraction , iii) simultaneously separating C8 and C10 fractions and recycling thereof into the reactor , and iv) separating residues comprising ≥ C12 fractions , spent catalyst, polymer material and quench media ,from the process ,wherein the solvent is separated in any of the steps i) -iv) and/or in an additional step.
