Abstract
REFERIDO A UN PROCESO PARA RECUPERAR EL ACEITE DEL PROCESO DE SECADO POR PULVERIZACION (PSP) DE UNA EMULSION O MICROEMULSION DE AGUA EN ACEITE QUE CONTIENE UN POLIMERO CON AGREGADO DE VINILO SOLUBLE EN AGUA, QUE COMPRENDE: A) CONDENSAR EL ACEITE Y EL AGUA GENERADOS POR DICHO (PSP) USANDO UN CONDENSADOR POR PULVERIZACION PARA OBTENER ACEITE CONDENSADO Y AGUA CONDENSADA, DONDE DICHO (PSP) COMPRENDE LAS ETAPAS DE: SECAR POR PULVERIZACION LA EMULSION O MICROEMULSION EN UN FLUJO DE GAS CON UN TIEMPO DE RESIDENCIA ENTRE 8s Y 120s, RECOGER LAS PARTICULAS POLIMERICAS RESULTANTES Y ADICIONALMENTE AGREGAR UN ACIDO, REGULADOR O BASE A DICHA EMULSION O MICROEMULSION ANTES O DURANTE EL (PSP) PARA PROPORCIONAR A DICHAS PARTICULAS POLIMERICAS UN pH ENTRE 1 Y 11 AL MOMENTO DE DISOLVERSE EN AGUA; B) SEPARAR EL ACEITE CONDENSADO DEL AGUA CONDENSADA; Y C) PURIFICAR EL ACEITE RECUPERADO CON UN LIQUIDO ACUOSO, TAL COMO UNA SOLUCION DE ACIDO SULFURICO, PARA OBTENER UN ACEITE PURIFICADO SUSTANCIALMENTE LIBRE DE SUSTANCIAS QUE DEBILITAN LA POLIMERIZACION Y ADECUADO PARA USARSE EN POLIMERIZACIONES SUBSIGUIENTES
