Abstract

MEZCLAS DE GASES MULTICOMPONENTES QUE CONTIENEN: (1) HIDROGENO COMO COMPONENTE PRIMARIO, (2) UN COMPONENTE CLAVE SECUNDARIO QUE SE ABSORBE MAS FUERTEMENTE QUE EL HIDROGENO, Y (3) UNA CANTIDAD MENOR DE UNO O MAS COMPONENTES TERCIARIOS DILUIDOS ABSORBIDOS MENOS FUERTEMENTE QUE EL COMPONENTE CLAVE SECUNDARIO, SE SOMETEN A UNA ABSORCION SELECTIVA EN UN CICLO DE ABSORCION POR OSCILACION DE PRESION ADIABATICA (PSA) PARA LA RECUPERACION SEPARADA DEL HIDROGENO DE ALTA PUREZA Y DEL COMPONENTE SECUNDARIO. UN EJEMPLO DADO LO ENCONTRAMOS EN EL TRATAMIENTO DEL GAS QUE FLUYE DE UN CONVERTIDOR DE CAMBIO EN UNA PLANTA DE TRANSFORMACION DE HIDROCARBUROS, DONDE EL HIDROGENO Y EL DIOXIDO DE CARBONO SE RECUPERAN SEPARADAMENTE COMO COMPONENTES CLAVES LIBRES SUSTANCIALMENTE DE COMPONENTES MENORES DILUIDOS TALES COMO EL METANO, EL MONOXIDO DE CARBONO Y EL NITROGENO.
