Abstract:
1. A chemical looping deoxygenation plant for deoxygenating the flue gas resulting from oxy-fuel combustion reactions for implementing a chemical looping deoxygenation process for deoxygenating the flue gas resulting from oxy-fuel combustion reactions, which comprises: a first step during which said flue gas is stripped of its oxygen by trapping said oxygen via the oxidation of an oxygen transport material, thus producing a main stream of flue gas with a reduced oxygen content; and a second step also producing flue gas which can join the main flue gas stream and during which the material oxidized in the first step is reduced and regenerated by reacting with fuel so as to be used again in said first step, wherein said chemical looping deoxygenation plant comprises: an oxidation reactor, comprising an oxy-fuel combustion flue gas feed means, an oxygen-reduced flue gas recovery means and a means for injecting the oxidized material into the regeneration reactor; and a regeneration reactor comprising a means for feeding the oxidized material coming from the oxidation reactor, a fuel feed means and a means for regenerating the oxidized material.
