Abstract
A process for separating at least two liquid phases which are at least partially non miscible is characterized in that after reacting, a polyphase effluent is settled in at least two distinct settling zones arranged in parallel, each of these settling zones containing at least one settler. The feed to be treated is sent to reactor R via a means for circulating fluids P via line 1. The effluent leaves the reactor via line 2 and is separated into two fractions. One fraction is sent to a settling zone a) via line 3; the other fraction is sent to a settling zone b) via line 4. The heavy phase from settling zone a) is sent to the reactor via line 7 and the heavy phase of the settling zone b) is sent to the reactor via line 6. The light phase from settling zone a) is sent to line 8, and rejoins fresh feed supply line 1. The light phase from settling zone b) is evacuated from the circuit via line 5.
