Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA REGENERACION DE TIERRAS DE BLANQUEO VICIADAS, QUE COMPRENDE UN TRATAMIENTO DE CALOR OXIDANTE EN EL QUE LA CANTIDAD DE OXIGENO SUMINISTRADA EXCEDE AL REQUERIMIENTO ESTEQUIOMETRICO DE OXIDACION COMPLETA DE TODOS LOS ORGANICOS PRESENTES EN LA TIERRA DE BLANQUEO VICIADA, EN DONDE LA TIERRA DE BLANQUEO VICIADA Y EL OXIGENO PASAN A TRAVES DE UN LECHO FLUIDIZADO ESTACIONARIO DE MATERIAL GRANULADO INERTE. EL FLUIDIZADO ESTACIONARIO DEBERIA SER TAN ELEVADO COMO PARA LIMITAR LA TEMPERATURA EN EL ESPACIO LIBRE A MENOS DE 1000 (GRADOS) C. DE HECHO, SE HA AVERIGUADO QUE, SI EL LECHO FLUIDIZADO NO ES LO SUFICIENTEMENTE ALTO, EL OXIGENO REQUERIDO PARA QUEMAR EL CONTENIDO ORGANICO DE LA TIERRA DE BLANQUEO VICIADA DEBERIA ELIMINAR LA TIERRA DE BLANQUEO EN POLVO DEL LECHO EN LA FASE DE OXIDACION INCOMPLETA DE LOS ORGANICOS PRESENTES EN LA TIERRA, DANDO COMO RESULTADO UNA ELEVACION DE TEMPERATURA INCONTROLADA EN EL RECALENTAMIENTO DEL ESPACIO LIBRE Y LOCALDE LA TIERRA DE BLANQUEO.
