Zusammenfassung:	A process for removing sulfur dioxide from flue gas is disclosed. After passing through a precipitator to remove particulate material, the flue gas is conducted continuously through a fixed bed solid-gas contacting device containing activated carbon or natural zeolite. The bed is regenerated continuously, thereby producing sulfuric acid which may be mixed with ground phosphate rock to produce normal superphosphate, or other by-products. SE DESCRIBE UN PROCEDIMIENTO PARA SEPARAR DIOXIDO DE AZUFRE A PARTIR DE GAS DE COMBUSTION. DESPUES DE ATRAVESAR UN PRECIPITADOR PARA SEPARAR EL MATERIAL EN PARTICULAS, EL GAS DE COMBUSTION SE CONDUCE DE MANERA CONTINUA A TRAVES DE UN DISPOSITIVO DE CONTACTO SOLIDO-GAS DE LECHO FIJO QUE CONTIENE CARBONO ACTIVADO O ZEOLITA NATURAL. EL LECHO SE REGENERA DE MODO CONTINUO, PRODUCIENDO CON ELLO ACIDO SULFURICO QUE PUEDE MEZCLARSE CON ROCA FOSFATADA MOLIDA PARA PRODUCIR SUPERFOSFATO NORMAL U OTROS PRODUCTOS SECUNDARIOS.
