Abstract

PROCEDIMIENTO PARA LA RECUPERACION DE ESTIROL MONOMERO A PARTIR DE RESIDUOS DE PLASTICO ("BASURA") QUE CONTIENE POLIMERO DE ESTIROL MEDIANTE DESPOLIMERIZACION TERMICA. LA BASURA DE FORMA LIQUIDA O SOLIDA EN UN LECHO TURBILLONARIO SE TRANSPORTA EN UN TRANSMISOR TERMICO SOLIDO, CON UN TIEMPO DE PERMANENCIA MEDIA DE AL MENOS 60 SEG. SIENDO CRAQUIZADO O DESPOLIMERIZADO Y OBTENIENDOSE EL PRODUCTO DESEADO A PARTIR DE LOS PRODUCTOS DE CRAQUIZACION EN FORMA GASEOSA. CON PREFERENCIA SE UTILIZA COMO TRANSMISOR TERMICO SILICATO DE ALUMINIO-MAGNESIO Y COMO GAS DE ACCIONAMIENTO PARA EL MANTENIMIENTO ADECUADO DEL LECHO TURBILLONARIO EN EL PROCESO DE DESPOLIMERIZACION C1 CARBURO CONFIGURADO COMO PRODUCTO INTERMEDIO, QUE PUEDE SER GUIADO AL CIRCUITO.
