Abstract

UN PROCEDIMIENTO PARA RECUPERAR RESIDUOS SULFUROSOS DERIVADOS DE LA PURIFICACION DEL ESTIRENO, QUE COMPRENDE LOS SIGUIENTES PASOS CONSECUTIVOS: A) AGREGAR DICHOS RESIDOS SULFUROSOS A UN GAS-OIL;B) SUJETAR LA MEZCLA RESULTANTE A UN PROCEDIMIENTO DE CRAQUEO TERMICO A UNA TEMPERATURA SUPERIOR A 400*C; C) EJECUTAR UNA DESTILACION FRACCIONADA DE LA MEZCLA ASI TRATADA; D) SUJETAR LA FRACCIONDE DESTILADO CON UNA TEMPERATURA DE EBULLICION COMPRENDIDA ENTRE 140*C Y 390*C, A UN PROCEDIMIENTO DE HIDRODESULFURACION CATALITICA; Y E) RECUPERAR EL AZUFRE ELEMENTAL DEL HIDROGENO SULFURADO ASI OBTENIDO.A PROCEDURE FOR RETRIEVING SULFID WASTE DERIVED FROM STYRENE PURIFICATION, WHICH INCLUDES THE FOLLOWING CONSECUTIVE STEPS: A) ADD SUCH SULFID WASTE TO A GAS-OIL; * C; C) EXECUTE A FRACTIONAL DISTILLATION OF THE MIXTURE ASI TREATED; D) SUBJECT THE DISTILLED FRACTION WITH A BOILING TEMPERATURE INCLUDING BETWEEN 140 * C AND 390 * C, TO A CATALYTIC HYDRODESULFURATION PROCEDURE; AND E) RECOVER THE ELEMENTAL SULFUR OF THE SULFURATED HYDROGEN SO OBTAINED.
