Abstract
The invention concerns a process for the oligomerization of ethylene into alpha-olefins, comprising a step for the oligomerization of ethylene, a step for deactivation of the catalyst, a and step for separation of the products, the reactor being provided with a cooling loop (100, 101, 102) by means of which at least a portion of the reaction effluent is moved through at least two switchable heat exchangers, said heat exchangers being cleaned alternately by means of an integrated cleaning device.
