  • Non-destructive method for determining the residual holding capacity of an adsorbent filter and associated test bench
    Patent number: 11958021
    Abstract: A method for determining residual filtration capacity of an adsorbent filter includes: selecting probe and carrier gases; at a given operating temperature, pressure and hygrometry, selecting injection parameters including sudden probe gas concentration variation in the carrier gas for a reference filter; injecting the probe and carrier gases into the reference filter per the injection parameters and measuring the change of probe gas concentration, downstream of the reference filter, for different known reference filter saturation levels, for a filter under test; injecting the probe and carrier gases into the filter under test according to the injection parameters and measuring the concentration change of probe gas, downstream of the filter under test; comparing the concentration change of the probe gas for the filter under test and the reference filter, for determining a saturation value of the filter under test; and deducing the residual filtration capacity of the filter under test.
