This depends on how many cells your factory has, the condition of those cells, the maintenance costs, the administrative costs, and the expenses required for evaporation
There are three concepts for the most economical current (current density): 1. The current density at the lowest cost for caustic soda； 2. Current density at which the total factory profit is highest with no increase in investment ； 3. Current density with low social investment but high social benefits. 1. The current density at the lowest cost for caustic soda is: the square root of [fixed costs ÷ (0.7198 × alternating current electricity price × number of electrolyzers × anode area of the electrolyzers × voltage gradient)]. 2. Current density at which the total factory profit is highest with no increase in investment: the optimal current density including the benefits from chlorine products. 3. Current density resulting in low social investment but high social benefits: the square root of {Investment per unit electrode area × transformation efficiency × (1 – auxiliary investment per unit electrode area related to current density) ÷ [Indirect investment per 1 KW of AC power × cathode current efficiency × (cell voltage gradient – utilization coefficient of energy generated by the current in the cell) × electrolyte voltage gradient].} For specific details, please refer to the thread on \"Chlor-alkali Technology\" on the forum: http://bbs.hcbbs.com/thread-3622-1-4.html
Please first specify the number of electrodes, membrane area, and other details! It’s impossible to answer such a foolish question! Please read the instructions first! http://bbs.hcbbs.com/thread-30498-1-1.html
Is your electrolyzer a diaphragm cell or an ion-exchange membrane cell? How large is the electrode area?
Based on the current value mentioned by the poster, it should be an ion exchange membrane; the current required for such a membrane is much higher than this value. Different situations require different answers. The original poster didn’t mention the electrolyzer model, the area of each cell, or the total number of cells per circuit... which really makes it difficult to answer: L
Additional note from LZ: For 80 units of Type 30-Ⅲ metal-anode diaphragm electrolyzers, what is the most appropriate current level for control?
