METHOD FOR THE IMPROVEMENT OF CURRENT EFFICIENCY IN ELECTROLYSIS

摘要

The invention relates to a method for the improvement of current efficiency in electrolysis. According to the method, a theorical cell volatge is first calculated, which is compared with the measured volatge. The cumulative difference between the theorical and measured cell voltage is monitored constantly and when this difference is proportioned to the current efficiency, information on the status of the process can be obtained continually. A decrease in current efficiency is a clear indicator of short circuits between the electrodes, and by means of the method according to the invention, it is possible to concentrate the short circuit removal work onto the correct cell groups, from the point of view of the current efficiency of the electrolysis.
