Abstract
UN PROCESO PARA PRODUCIR DIMETIL CARBONATO SE LLEVA A CABO MEDIANTE UN PRIMER PASO DE HACER REACCIONAR CATALITICAMENTE MONOXIDO DE CARBONO CON METIL NITRITO PARA PRODUCIR DIMETIL CARBONATO; UN SEGUNDO PASO DE ABSORBER DIMETIL CARBONATO CONTENIDO EN UNA FRACCION GASEOSA EXTRAIDA DEL PRIMER PASO POR MEDIO DE OXALATO DIMETIL; UN TERCER PASO DE REGENERAR METIL NITRITO PONIENDO EN CONTACTO MONOXIDO DE NITROGENO CONTENIDO EN UNA FRACCION GASEOSA EXTRAIDA DEL SEGUNDO PASO CON UN GAS MOLECULAR QUE CONTENGA OXIGENO Y ALCOHOL METILO; UN CUARTO PASO DE RECOGER DIMETIL CARBONATO DESTILANDO UNA FRACCION LIQUIDA EXTRAIDA DEL SEGUNDO PASO; Y UN QUINTO PASO DE RECUPERAR METIL NITRITO A PARTIR DE UN GAS DE PURGADO QUE CONSISTE EN UNA PORCION DE GAS REGENERADO EXTRAIDO DEL TERCER PASO ABSORBIENDO METIL NITRITO DEL GAS DE PURGADO POR ALCOHOL METILO PARA PROPORCIONAR UNA FRACCION LIQUIDA QUE CONTENGA METIL NITRITO Y UNA FRACCION GASEOSA QUE CONTENGA MONOXIDO DE NITROGENO Y PONER LA FRACCION GASEOSA EN CONTACTOCON UN OXIGENO MOLECULAR Y ALCOHOL METILO PARA CONVERTIR EL MONOXIDO DE NITROGENO DE LA FRACCION GASEOSA EN METIL NITRITO Y PARA ABSORBER ESTE METIL NITRITO POR METIL ALCOHOL, A LA VEZ QUE SE RECUPERAN METIL NITRITO Y MONOXIDO DE NITROGENO DEL GAS DE PURGADO Y SE REUTILIZAN CON ALTA EFICIENCIA EN UN ALTO NIVEL DE SEGURIDAD.
