Abstract

SE PRESENTA UN METODO PARA EL TRATAMIENTO DE SUELOS CONTAMINADOS CON HIDROCARBUROS MEDIANTE UNA HIDROLISIS Y/U OXIDACION QUIMICA DE LOS HIDROCARBUROS QUE SE ENCUENTRAN EN EL SUELO CONTAMINADO CON HIDROCARBUROS. EL METODO CONSISTE EN UTILIZAR CAL PREVIAMENTE ACONDICIONADA CON UN NUEVO AGENTE HIDROFOBIZANTE. EL NUEVO AGENTE HIDROFOBIZANTE CONSTA DE UNA MEZCLA LIQUIDA DE UNA MEZCLA ESPECIFICADA DE ACIDOS GRASOS LIQUIDOS QUE TIENEN DE 6 A 12 ATOMOS DE CARBONO Y UNA MEZCLA ESPECIFICADA DE GLICERIDOS DE ACIDOS GRASOS QUE TIENEN DE 8 A 18 ATOMOS DE CARBONO. LA CAL ACONDICIONADA SE MEZCLA CON EL SUELO CONTAMINADO CON HIDROCARBUROS, HUMEDO, PREACONDICIONADO FISICAMENTE, ES DECIR, CON UN TAMAÑO DE GRANO MAXIMO DE 5 CM, PROPORCIONANDO LA MEZCLA UN GRADO DE DISPERSION CON UN NIVEL CASI MICROSCOPICO. UNA CARGA DE LA CAL/SUELO ACONDICIONADOS Y MEZCLADOS SE TRANSPORTA A UN RECIPIENTE DE REACCION INCLINADO Y CERRADO DONDE SE LLEVA A CABO LA HIDRATACION DE LA CAL. EL CALOR DE LA REACCION DE HIDRATACION SE RETIENE DENTRO DEL RECIPIENTE PARA QUE SE PUEDE PUEDA TENER LUGAR LA HIDROLISIS DEL ACONDICIONADOR DE ACIDO GRASO Y/O DE LOS CONTAMINANTES HIDROCARBUROS QUE SE ENCUENTRAN EN EL SUELO. SE INTRODUCE SIMULTANEAMENTE SUSTANCIALMENTE AIRE O AIRE ENRIQUECIDO CON OXIGENO EN EL RECIPIENTE DE REACCION JUNTO CON VAPOR Y/O AGUA SEGUN LO REQUIERAN LAS REACCIONES QUIMICAS, PARA ASI LLEVAR A CABO UNA OXIDACION A TEMPERATURA INTERMEDIA, SIN LLAMAS, DE LOS HIDROCARBUROS O DE SUS PRODUCTOS DE DEGRADACION HIDROLIZADOS. EL PRODUCTO DEL SUELO DESCONTAMINADO SE DESCARGA DEL RECIPIENTE DE REACCION A BASE DE HACER PASAR AL PRODUCTO DEL SUELO, A MODO HIDROFOBICO CON POLVO, EN SECO, A TRAVES DE LA ZONA DE CALENTAMIENTO DONDE ES PULVERIZADO CON UN SURFACTANTE. AL SOLIDO TRATADO CON EL SURFACTANTE SE LE HACE PASAR A UN MEZCLADOR DONDE SE MEZCLA CON AGUA SUFICIENTE COMO PARA OBTENER UN PRODUCTO LIMPIO, SUSTANCIALMENTE SIN POLVO.
