May I ask the experts: is the oxygen cathode technology in the chlor-alkali industry mature?
Thread Content
As the title suggests, I would like to know whether oxygen cathode technology is currently mature and stable in industrial applications By how much is the cost higher than that of existing electrolyzer technologies? Do domestic companies have relevant technology? Thank you to all the experts! ! ! Waiting for an answer....:victory:
Oxygen cathode technology is quite mature. At present, Binhua Group has a production line with a capacity of 40,000 tons, and its electricity consumption is approximately 1,600 kWh per ton of caustic soda produced. The investment is higher compared to ordinary ion-exchange membrane electrolysis. The oxygen cathode at Binhua has been in operation for over 4 years.
Sure, there are some who don’t know what product you intend to produce
Are there any relevant resources you can recommend? :handshake
Let me introduce some relevant resources!
Why hasn’t such a great product been promoted?
Oxygen cathode electrolyzers are expensive; it is said that their price is roughly 2-3 times that of ordinary electrolyzers； An additional air separation unit is needed to produce oxygen for supply to the electrolyzer, where the hydrogen is reacted ； The power consumption can be as low as 1400 KW.h/t.
Aren’t many companies these days in the chlorine-consuming downstream sector? There are few downstream applications for hydrogen consumption, and many of them require significant investment. Is Covestro a company that is better to work for?
