Abstract
OXIDACION DE IONES DE AMONIO Y DE CARBONO ORGANICO EN AGUAS RESIDUALES QUE CONTIENEN IONES DE AMONIO Y CARBONO ORGANICO CON ACIDO NITRICO A 100 HASTA 350 (GRADOS) C, PARA LO CUAL SE AJUSTA LA RELACION MOLAR DEL CARBONO ORGANICO AL NITROGENO AMONIACAL POR ADICION DE CARBONO ORGANICO O DE NITROGENO AMONIACAL EN UN MARGEN DESDE 0,3:1 HASTA 4:1. EN UNA CONFIGURACION PREFERIDA, QUE POR EJEMPLO, SE REPRODUCE EN LA FIGURA, SE TRANSPORTA EL AGUA RESIDUAL, LA CUAL SEGUN EL CONTENIDO TOC SE PUEDE ENRIQUECER CON C ORGANICO, POR MEDIO DE LA TUBERIA (1), EN CASO NECESARIO DESDE UN TANQUE INTERMEDIO (2) CON UN BOMBA (3) A TRAVES DE UN CAMBIADOR DE CALOR (4), EN EL CUAL SE PRECALIENTA, POR EJEMPLO, A 270 (GRADOS) C. A CONTINUACION SE RECALIENTA EL AGUA RESIDUAL PRECALENTADA POR INYECCION DIRECTA DE VAPOR A LA ELEVADA PRESION DE 100 BAR POR LA TUBERIA (5) O POR UNA CALEFACCION INDIRECTA A 290 (GRADOS) C. DESPUES DEL AJUSTE DE LA CONCENTRACION DE ACIDO NITRICO NECESARIO PARA LA REDUCCION DEL AMONIO, POR EJEMPLO, POR MEDIO DE UNA TUBERIA (6) EN EL AGUA RESIDUAL CALIENTE A 290 (GRADOS) C, SE TRANSPORTA ESTE AGUA A TRAVES DE UN REACTOR (7) SIN MEZCLA EN RETORNO (POR EJEMPLO, REACTOR TUBULAR CON DEFLECTORES QUE ESTAN RECUBIERTOS DE TITANIO). DESPUES DE UN TIEMPO DE PERMANENCIA DE, POR EJEMPLO, 5 A 10 MINUTOS, SE ENFRIA LA SOLUCION DE REACCION EN CONTRACORRIENTE CON LA ALIMENTACION Y SE EXPANDE EN UN SEPARADOR (8). POR MEDIO DE UNA TUBERIA (9) SE EVACUA EL AGUA RESIDUAL, MEDIANTE UN TANQUE INTERMEDIO (10) Y UN CAMBIADOR DE CALOR (11).
