Abstract

In an oligomerization apparatus comprising at least two oligomerization reactors, at least portions of product streams from two reactors are separated in the same separator vessel; a liquid product stream from the first oligomerization reactor is fed to a fractionation column and a side cut from the fractionation column feeds the second oligomerization reactor.
