Abstract

La presente invención se refiere a un procedimiento para la descontaminación de materiales tales como suelo, sedimentos y lodos contaminados con contaminantes orgánicos, comprendiendo el procedimiento las etapas de: a) separar el material en una fracción sólida y una fracción líquida, cuando hay líquido presente; b) lixiviar la fracción sólida con un solvente de lixiviación para obtener un solvente de lixiviación contaminado y una mezcla de sólidos y solvente de lixiviación descontaminados: c) separar el contaminante del solvente de lixiviación contaminado con un solvente de separación para concentrar los contaminantes y d) cuando haylíquido presente en el material, adsorber los contaminantes residuales de la fracción líquida en los sólidos descontaminados. Para producir líquidos descontaminados y sólidos contaminados. Un procedimiento para la descontaminación de contaminados con compuestos orgánicos hidrofóbicos, comprendiendo el procedimiento las etapas de: a. proporcionar una mezcla de sólidos con agua y contaminante que incluye compuestos orgánicos hidrofóbicos; b. lixiviar los sólidos con solventes para obtener solvente contaminado y agua y una mezcla de sólidos descontaminados y solvente, por medio de i, remover agua de la mezcla de la etapa a) con un solvente hidrofílico y contaminante, ii) desalojar el contaminante de la primera corriente sólida con una comezcla de solvente hidrofílico y un solvente hidrofóbico, para obtener una segunda corriente líquida de los dos solventes y la mayor parte del contaminante y una segunda corriente sólida de los sólidos, los dos solventes, y el contaminante restante; y iii, desalo jar de la segunda corrientelíquida con solvente hidrofílico, para obtener una tercera corriente líquida de los dos solventes y el contaminante restante y una tercera corriente sólida descontaminada de sólidos y solventes hidrofílico, c. separar el contaminante de por lo menos dos de las corrientes líquida cib el solvente hidrofóbico, para obtener una producción del solvente hidrofílico descontaminado y una producción de solvente hidrofóbico y contaminante concentrado; y d) separar el solvente hidrofílico de la tercera corriente sólida, para obtener sólidos descontaminados y solvente hidrofílico descontaminado.
