How can manufacturers reduce power consumption?

The problem is huge! Generally speaking, it is divided into two aspects: electrical and process-related elements. 1. Starting from the rectifier transformer, this includes the selection of transformers and rectifiers, optimal layout of equipment, choice of copper bars, treatment of surfaces and joints, control of conduction angle, power factor, rectification efficiency, etc. 2. In terms of the process: (1) Starting with the comparison of different project options, deciding on which manufacturer to use (Beihua Machinery, Asahi Kasei, Wood, Chlorine Engineering, INOES, etc.), what type of electrolyzer to select (NCH, NCZ), and what type of membrane to use (NAFION, Aciplex, FLEMION) – all of these factors are directly related to power consumption (AC, DC); determining the scale of the operation... optimizing the site layout...; selecting the chlorine treatment process: fully packed bed, packed bed + bubble column ； Single tower, double tower, triple tower, or otherwise, the magnitude of the pressure drop is directly related to the power consumption of the chlorine compressor ； Selection of compressor type: turbine or liquid ring type; there is a significant difference in efficiency and energy consumption ； Power distribution type: high-voltage motor or low-voltage motor..... Selection of liquefaction method: choice of energy saver ； Selection of low, medium, and high-pressure versions..... ； Selection of liquid chlorine transportation methods: submersible pumps, shielded pumps..... ； Selection of the process for the exhaust gas hydrochloric acid plant: hot water type, steam type... ； Selection of hydrogen compressors.......; Selection of utility systems: circulating water, ........... (2) Production control – How to stabilize the quality of brine, as well as its pH, SS, and heavy metal content, as much as possible ； How to minimize the number of abnormal parking incidents as much as possible ； How to improve the management system for electrolytic cells ； How to stably maintain the operating conditions of the electrolyzer: load, pressure, temperature..... ； It’s really in every aspect; simply comparing DC power consumption is meaningless.

Upstairs, the topic of energy conservation and cost reduction across the entire factory was discussed in general terms; it was comprehensive but not detailed. It’s not easy to cover everything related to energy conservation and cost reduction in detail. It seems appropriate for someone knowledgeable to write a paper on this subject. Experienced colleagues, who among you is willing to take on this honorable task? We support you!:victory: :victory:

Improve the quality of the saline solution to keep the control parameters of the electrolyzer within reasonable ranges, and ensure proper contact between the conductors.

To reduce the power consumption of electrolyzers, there are many factors to take into account: 1. Starting with the selection of the electrolyzer, it is necessary to choose ones with high performance； 2. Choose a high-performance ion membrane ； 3. Selection of the rectifier ； 4. Connection of copper bars ； 5. Selection of equipment and pipelines related to the electrolyzer ； 6. Ensure the quality of the brine fed into the electrolyzer (the concentrated brine after the resin tower) ； 7. The operation of the electrolyzer should follow the instructions provided by the manufacturer; of course, if there are any doubts, it is necessary to communicate with each other in order to make improvements ； 8. Strengthen staff training to reduce errors and improve the ability to handle emergencies ； 9. Strengthen the management of leaks, spills, and other losses of fluid ； 10. Strengthen the control of process parameters.

In fact, after the selection of the electrolyzer and related equipment, all that the operator can do is: 1. Ensure the effectiveness of the resin tower, thereby guaranteeing the quality of the brine fed into the electrolyzer, extending the service life of the ion exchange membrane, and achieving high current efficiency； 2. The operation of the electrolyzer must be carried out strictly in accordance with the procedures ； 3. Strengthen staff training to improve their competence, thereby reducing losses caused by errors in operation as well as the number of start-up and shutdown operations; 4. Improve the management of leaks and other forms of waste ； 5. Strengthen the control of alkali concentration to prevent losses in its concentration; 6. Improve the ability to handle emergencies and extend the service life of the equipment ； 7. Tighten the copper bars to reduce voltage loss; 8. Reduce the voltage loss of the electrolyzer with respect to ground.
