Abstract

<p>LA INVENCIÓN ANTERIOR SE RELACIONA CON UN PROCESO DE CALCINACIÓN DE PARTÍCULAS DE MINERAL QUE CONTIENEN CARBONO Y/O AZUFRE, DONDE LAS PARTÍCULAS SE ALIMENTAN AL REACTOR PARA SU CALCINACIÓN. SE INTRODUCE UN GAS QUE CONTIENE OXÍGENO, DONDE LAS PARTÍCULAS SE CALCINAN EN UN LECHO FLUIDIZADO A UNA TEMPERATURA DE 500 A 1.000 °C DURANTE AL MENOS 10 SEGUNDOS Y DONDE LAS PARTÍCULAS CALCINADAS SE EXTRAEN DEL REACTOR. LAS PARTÍCULAS TIENEN UN CONTENIDO MÁXIMO DE AGUA DE 2 % EN PESO Y SE INYECTAN NEUMÁTICAMENTE AL LECHO FLUIDIZADO.</p><p> THE PREVIOUS INVENTION IS RELATED TO A CALCINATION PROCESS OF MINERAL PARTICLES CONTAINING CARBON AND / OR SULFUR, WHERE THE PARTICLES FEED TO THE REACTOR FOR CALCINATION. A GAS CONTAINING OXYGEN IS INTRODUCED, WHERE THE PARTICLES ARE CALCINATED IN A FLUIDED MILK AT A TEMPERATURE OF 500 TO 1000 ° C DURING AT LEAST 10 SECONDS AND WHERE THE CALCINATED PARTICLES ARE REMOVED FROM THE REACTOR. THE PARTICLES HAVE A MAXIMUM WATER CONTENT OF 2% BY WEIGHT AND ARE INJECTED INTO THE FLUIDIZED MILK. </p>
