1. A plant for chemical looping combustion of a solid hydrocarbon feedstock generating particles of unburnt residues and employing particles of an oxygen-carrying solid, the plant comprising:
a reduction reactor operating as fluidized bed in order to carry out the combustion of the solid hydrocarbon feedstock in contact with the particles of the oxygen-carrying solid, the reactor having a parallelepiped shape;
an oxidation reactor operating as fluidized bed in order to oxidize the reduced particles of the oxygen-carrying solid originating from the reduction reactor by bringing into contact with an oxidizing gas; and
a solid/solid separator surmounting the reduction reactor in order to separate the particles of the oxygen-carrying solid from particles of unburnt residues contained in a gas/solid mixture resulting from the reduction reactor, the solid/solid separator comprising:
a chamber of parallelepipedal shape comprising
a lower part operating as dense phase and an upper part operating as dilute phase;
at least one inlet of parallelepipedal shape for the gas/solid mixture originating from the reduction reactor, the at least one inlet emerging in the upper part of the chamber and being equipped at a top of the at least one inlet with means for distribution of the gas/solid mixture in the chamber which extend over the entire length of the at least one inlet;
at least one drain placed in the lower part of the chamber;
at least one outlet located in the upper part of the chamber.
