Abstract
Process for desulfurizing combustion gas wherein the gas is fractionated into at least two flows which pass through distinct passageways (4 and 5) and receive particles of a solid desulfurizing agent coming from distinct injectors (7 and 8) . The two particle-charged flows meet (9) , are separated again (10 and 11) and meet again thereafter (12). The process can be repeated several times. The final mixture is carried off and fractionated into desulfurized gas and recovered solid particles.
