Abstract
UN PROCEDIMIENTO PARA LA DETERMINACION CUANTITATIVA DEL CONTENIDO DE HIDROGENO PURO Y/O UNIDO EN MEZCLAS GASEOSAS QUE LLEVAN HIDROGENO PREFERIBLEMENTE EN ATMOSFERAS GASEOSAS QUE CONTIENEN AMONIACO O CARBONO O DE HORNOS DE TRATAMIENTO TERMICO, DE UNA MANERA RAPIDA, SENCILLA Y BARATA SE PUEDE DETERMINAR EL CONTENIDO DE HIDROGENO TAMBIEN A ELEVADAS TEMPERATURAS POR ENCIMA DE 500° C, Y SE POSIBILITA UNA DETERMINACION DIRECTA DE LAS CARACTERISTICAS DEL PROCESO, SE PROPONE QUE SE SEPARE EL HIDROGENO MEDIANTE UNA MEMBRANA SELECTIVA (1) DE LA MEZCLA GASEOSA, FORMANDOSE UNA CORRIENTE GASEOSA (16) QUE RODEA LA MEMBRANA (1) SE MIDE LA PRESION PARCIAL DEL HIDROGENO SEPARADO, Y SE CONSIDERA COMO MEDIDA PARA EL CONTENIDO EN HIDROGENO EN LA CORRIENTE GASEOSA, Y SE ELIGE LA VELOCIDAD DE LA CORRIENTE GASEOSA (16) A LO LARGO DE LA SUPERFICIE (18) DE LA MEMBRANA (1) DE UNA ALTURA QUE IMPIDA EN LA CORRIENTE (16) LA FORMACION CATALITICA DE MAS HIDROGENO. ADEMAS SE DESCRIBE UN DISPOSITIVO PARA LLEVA A CABO EL PROCEDIMIENTO.
