Abstract
SE PRESENTA UN METODO PARA MEJORAR LA CALIDAD DEL RECICLADO DE CIERTOS RESIDUOS A BASE DE MODIFICAR LA SEPARACION DE MATERIALES ALCANOS Y TIPO ALCANO Y DE LAS IMPUREZAS QUE CONTIENEN CARBONILO DEL RECICLADO DURANTE LA PRODUCCION DE ACIDO ACETICO MEDIANTE LA CARBONILACION DE METANOL. LA MEJORA CONSISTE EN PONER EN FUNCIONAMIENTO UNA COLUMNA SEPARADORA DE LAS YA EXISTENTES A MODO DE REFLUJO Y SEPARAR EL RESIDUO DE LA MISMA A BASE DE AÑADIR AGUA. EL METODO REDUCE TAMBIEN EL VOLUMEN DE DESECHO DE REACTANTES RECICLABLES POTENCIALMENTE VALIOSOS.
