PROCESS AND APPARATUS FOR OLIGOMERIZATION IN MULTIPLE STAGESWITH SINGLE FRACTIONATION COLUMN

摘要

In an oligomerization process comprising at least two oligomerization reactors, at least portions of product streams from two reactors are separated in the sam e separator vessel. In an embodiment, 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.
