  • Patent number: 5015345
    Abstract: The present invention discloses a method for identifying defective ion exchange membranes installed in monopolar and/or bipolar electrolyzers for chlor-alkali production. The method of the present invention comprises reducing the electric load of the electrolyzer down to 2 to 10% of the normal load and under these reduced load conditions, a measurement of the single electric current load absorbed by each elementary cell in a monopolar electrolyzer is effected as well as the measurement of the single electric voltage of the elementary cell in the case of bipolar electrolyzers. The method further comprises calculating the deviations of the single current or voltages with respect to average values. All membranes which present values comprised between a determined threshold value are considered as suitable for operation.
