It’s okay, but titanium pipes cannot be used for saltwater pipelines. Our company plans to use glass-lined steel pipes, but the official approval from the company has not yet been obtained
No way, nowadays the pipelines in chlor-alkali and salt production plants are all made of titanium pipes – how could they not work?
What’s important when paying attention is the efficiency and cost
Using fiberglass to treat brine at room temperature is the preferred option, but since evaporation involves heat, it is recommended to choose titanium tubes for safety.
What kind of process is it? What’s the use of concentrated brackish water if it’s not mixed with water? Please explain, OP.
After evaporation, the brackish water is directly concentrated to a salinity of about 300 g/l and then reused in the electrolyzer; it seems that such devices indeed exist!
Hehe, from a cost perspective, it’s definitely not cost-effective! Steam is so expensive these days! The forum previously also had introductions to reverse osmosis, but they were not thorough enough. If multi-effect evaporation is used, the thermal efficiency remains quite high. (4-effect 3.2)
Titanium tubes can’t be used; you’ll find out once you try them. The titanium tubes in my company have all gone bad, just because the temperature exceeds 120 degrees. As long as the pH is slightly acidic, it’s fine, but even neutral conditions cause problems. My company has only that little amount of titanium tubes, and more than 2 million has been wasted needlessly
Reply to 5# guangruitai: It doesn’t work. My company is in a terrible state – as long as the pH is slightly acidic and the temperature exceeds 120 degrees, you’ll see the problems; my company has already wasted over 2 million
Little white rabbit upstairs, which company do you work for? Corrosion of titanium pipes in saltwater pipelines – some people don’t understand this; let’s explain it in more detail.
