    The present invention belongs to the technical field of centrifugal separation to separate carbon dioxide from combustion gases of fossil origin. OBJECTIVE OF THE INVENTION
    The objective of the present invention called "CENTRIFUGAL SEPARATOR OF C02 FROM COMBUSTION GASES", is the separation of carbon dioxide(C02), from the combustion gases by means of the centrifugation technique, inthe one in which the denser gas (C02) is separated from the less dense gas (N2) being displaced towards the periphery in a radial direction due to the centrifugal force and captured by means of a circular plate from whose center a conduit for the extraction of the C02 starts to be stored and / or hijacked. BACKGROUND OF THE INVENTION
    Currently known post-combustion procedures for separating or capturing C02 from combustion gases by centrifugation are based on technologies that do not make use of centrifugation. Technologies based on gas-gas centrifugation are known for uranium enrichment. The C02 capture technique proposed in this invention applicable to the post-combustion group consists of separating the C02 from the combustion gases by means of centrifugation, where C02 is partially recovered in a high percentage. Based on the procedures of known and cited conventional techniques, the technique object of the invention is unknown and innovative. BRIEF DESCRIPTION OF THE INVENTION
    The invention called "CENTRIFUGAL SEPARATOR OF C02 FROM COMBUSTION GASES" is based on separating the C02 from the nitrogen contained in the combustion gases by introducing the gas to be separated through a conduit that enters through an upper area close to the central axis of rotation of the cylinder. centrifugal, where the component of the most dense gas (C02) is fired by virtue of the centrifugal force or separated towards the periphery while the component of the less dense gas (N2) is retained in the area closest to the axis of rotation, in such so that the most dense gas is extracted from the periphery of the lower zone by means of a circular plate in whose center of rotation contains an extractor duct, and the less dense gas is extracted by the upper part in the zone close to the axis of rotation, where the centrifugal force is less than at the periphery.

    The CENTRIFUGAL SEPARATOR OF C02 FROM THE COMBUSTION GASES objectof the invention is made up of the following components:- centrifuge rotor (1) with a frustoconical appearance in the shape of an inverted bowl, whichcaused by the centrifugal force generated as a result of high speed rotation,separates the gases of higher density (C02) moving them towards the periphery of the rotor,lower density gases (N2).

    Outlet collector duct of the denser gas rich in C02 (3) and in turn, concentric internally to the collector duct of the less dense gas rich in N2 (4), are separated so that the gas of higher density (C02) is separated from the N2 and displaced towards the periphery of the rotor (1) due to the centrifugal force to which it is subjected, so that the C02 accumulated on the periphery of the rotor is displaced towards the lower zone of the centrifugal rotor (1) by the action of the centrifugal force, being captured by the circular C02 collector plate (2), being evacuated by the exit collector of the dense gas rich in C02 (3), while the lower density gas N2 is retained in the central zone of the rotor rotation shaft (1),

    The least dense N2-rich between cascade centrifuges (12) connects the outlet (4) of the primary separator with the inlet (5) of the secondary separator.
