  • Patent number: 5328674
    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.

  • Patent number: 5216966
    Abstract: A heat-generating plant comprising a combustion chamber (1), at least one convective exchange zone (4, 9), a desulfurization chamber (6) comprising at least one means (8) for injecting an absorbent and communicating with a chamber (13) linked to said first convective exchange zone (9), said separation chamber having at least one outlet (132, 133) for the spent absorbent and an outlet (14) for the depolluted gases. The plant also comprises :means (32) for regenerating the spent absorbent, andmeans (38, 41) intended to treat the absorbent and/or the regeneration gases coming from said regeneration means (32).A means (16) for the intermediate storage of the spent absorbent can also be provided in the plant.
