Abstract:
The invention relates to accelerated mixed gas integrity testing methods, devices, and systems for integrity testing wetted single and multi-layered porous materials., whereby the testing method is non-destructive to the porous materials being tested. The accelerated mixed gas integrity test method includes one or more of the following components: i) a permeate side gas purge component: ii) a permeate side volume reduction component; and iii) a permeate side circulation component. The invention is directed towards reducing the length of time necessary to complete the integrity testing of single and multilayered porous materials, elements and membranes.

Abstract:
Un método para evaluar la integridad de un material poroso cargado en un dispositivo de material poroso que comprende a) cargar un material poroso humectado en un dispositivo que tiene una carcasa para recibir el material poroso humectado, dando como resultado un material poroso humectado que tiene un lado de la alimentación y un lado del permeado; b) introducir una mezcla de gas comprimido de dos o más componentes de gas al lado de la alimentación del material poroso humectado, en el que los gases de alimentación tienen permeabilidades diferentes en el líquido usado para humectar el material poroso de manera que uno de los gases permea a través del líquido del material poroso humectado más rápido que el otro gas o gases utilizados; c) cargar el lado del permeado del volumen de material poroso con una mezcla de gases que tiene la composición esperada de gas permeado generado a partir de una membrana integral; d) ventilar el exceso de gas permeado y mantener un flujo de barrido de gas del lado de la alimentación; e) evaluar la concentración de la mezcla de gases en el lado del permeado; y f) comparar la concentración evaluada del gas permeado con el valor esperado de un dispositivo integral, en el que una desviación de la concentración esperada por encima de la cantidad predeterminada es una señal para un material poroso o dispositivo de material poroso no integral.
