Could the poster provide information on the production capacity of each cell, power consumption, current efficiency, the service life of the membrane and electrode sheets, as well as the investment required? A single high-density current operation alone does not provide enough information to understand the specifics.
What is the model of the ion membrane? It must be related to the ion membrane; we use Asahi Glass F802 as well as DuPont 2010 and 2030.
It depends on whether the models and specifications of the electrolyzers and membranes in your two companies are the same; their maximum load ratings differ. It’s best not to exceed the specified values, and you can also consult the manufacturers.
During the design process, the current for Process Package 890 was 18.08 KA. What model is your cell, so that we can make a comparison?
The current is indeed high; I was wondering if you could provide some information regarding this battery.
It should be related to the ion membrane; it depends on what model of ion membrane it is
The ion membrane in chlor-alkali plants can operate under overload conditions.

Reply 1# want777: It’s possible; the nBitac cells from Chlorine Engineering can achieve a current density of 6 kA, which corresponds to an operating current of 19 kA. Asahi Kasei’s membrane-gap cells can also operate at this current density. The loading conditions during the operation of an electrolyzer depend not only on the ion membrane but also on the structure of the cell and the electrode coatings; among these, the cell structure is the most critical factor, including technologies such as gas separation, uniform liquid distribution, and current distribution. In these aspects, the Japanese are far ahead of us. Ion membrane technology – as is well known, alas, I really hope that domestic products can be used on a large scale in industrial applications, and even more so that they can be utilized at high electric densities of 6 kA.
What model is the electrolyzer used in your sister company’s facility? Is it n-BiTAC or BiTAC? What model is your electrolyzer? For conventional chlorine production cells using n-BiTAC, the normal operating potential is 5.52, while the normal current level is 18.08. There is a 110% operational margin, so it’s possible to operate at 19 KA without issues; however, it’s essential to maintain good quality of the saltwater.
Some companies use a value of 19; upon communicating with them, it was found that the voltage is only 3.2, and the DC power consumption per unit is 3150
