Abstract

METODO PARA LA PRODUCCION DE OXIGENO GASEOSO. CONSISTE EN COMPRIMIR AIRE A 5-10 BARES, PASARLO A TRAVES DE TAMICES MOLECULARES PARA ELIMINAR EL CO Y EL AGUA, FRACCIONARLO EN UNA UNIDAD DE DESTILACION QUE CONSTA DE UNA COLUMNA QUE TRABAJA A 5-9 BARES Y OTRA QUE TRABAJA A 1,3-3 BARES, RETIRAR EL OXIGENO LIQUIDO DE LA COLUMNA DE BAJA PRESION, PONERLO A PRESION, VAPORIZAR EL OXIGENO Y CALENTAR EL VAPOR. EL ENFRIAMIENTO SE PRODUCE POR COMPRESION Y RECIRCULACION DEL AIRE.
