Abstract
The invention relates to the field of olefin oligomerization to obtain liner α-olefins, particularly to a method of separating olefin oligomerization products using an evaporator. The invention includes two embodiments of the method of separating the oligomerization reaction product streams. In accordance with the first embodiment of the invention, the oligomerization reaction product stream after the step of isolating an initial olefin is fed into an evaporator to the step of separating the oligomerization reaction product steam. In accordance with the second embodiment of the invention, the oligomerization reaction product stream after the step of isolating the initial olefin is separated into two streams, the first part of which is fed into the separation column, and the second part is fed into the evaporator. The invention allows to minimize a quantity of technological equipment contaminated by the by-product polymer.
