FIELD: electricity.
SUBSTANCE: invention relates to a method for failures tracking associated with a stream of feedstock gas and/or purification stream in electrolytic cells, batteries or systems, this tracking process is combined with precautionary measures to be taken in the event of such failures. In this case, (a) the current and/or voltage are monitored and controlled on a single battery, on all batteries or on one or more selected batteries of the electrolytic systems, (b) in case when the current, voltage or voltage-to-current ratio crosses its predetermined threshold value, the fault mode is found and the message is transmitted to the control system, and (c) the system voltage levels are controlled providing location within safe limits (safe mode limits), while tracking both current and voltage for failures detection in operation and transition to protective voltage levels in case of failure, the same power supply is used, the protective voltage between 600 and 1500 mV per cell is applied to each battery cell, and additional protection is provided by performing one or more of the following actions: (1) blowing potentially oxidizable electrodes with oxygen-free gases, (2) the electrolytic cell of the battery gradual cooling either by blowing gases, or by the passive heat output from the system and (3) maintaining the electrolytic voltage on each element of the plurality of cells and batteries at least until their temperature falls below the electrolytic cell electrodes oxidation threshold.
EFFECT: invention makes it possible to effectively monitor the failure operations associated with a raw or blowing-off gas stream.
