Abstract
Perfeccionamientos introducidos en una columna de hidrólisis utilizada en un proceso en cadena de conversión de diuranato de amonio, en que se disuelve UF(sub, 6) en agua hecha pasar a través de la columna, teniendo dicha columna una estructura de boquilla para gas montada en ella y que comprende un alojamiento que tiene un pasaje radial en un racor que es de longitud suficiente para extenderse dentro de dicha columna de modo que el gas de UF(sub, 6) que fluye a través de dichos pasajes es descargado directamente en el agua que fluye en dicha columna, caracterizados porque dicho alojamiento consiste en un metal resistente a la corrosión, conductor del calor, y está provisto de medios calentadores capaces de mantener la temperatura de dicho alojamiento a un nivel que evita la congelación del gas de UF(sub, 6) que fluye a su través, y porque una junta de tetrafluoretileno está asegurada a la cara de dicho alojamiento, y dicho racor está hecho de tetrafluoretileno y está fijado de manera separable a dicho alojamiento, estando la abertura axial de dicho racor en alineación con el pasaje axial que tiene en su extremo situado en dicho alojamiento enfrente de dicho racor un tapón separable que, al ser retirado, permite la inspección y limpieza del pasaje axial.
