Analysis and control requirements for TOC in saline water
Thread Content
We plan to use by-product salt. What are the TOC control requirements for chlor-alkali manufacturers? How is it detected and where are the analysis methods available? What is the cost? Those who have relevant knowledge, please share your opinions. Thank you!
Asahi Kasei in Japan requires the level to be less than 10 ppm; most companies do not have equipment for analyzing TOC, so our company sends the saline solution to Japan through an intermediary for analysis.
Well, the target for Asahi Kasei is less than 10PPM. Our company has just acquired a TOC analyzer, purchased from Beijing; it seems to be new, with an original price of 300,000 yuan
Is that so? Which company are you from? What are the analysis parameters like? Can it detect TOC in saline without being affected by salt levels? I would appreciate your guidance.
Here, we mainly test the raw salt in order to control the quality of the salt that enters the factory. I’m not exactly sure as to why it’s not affected by salt content – after all, I’m not involved in analysis work. My analyst colleague is taking a break; I’ll ask him for you when he gets back
Hello, we are also planning to use by-product salt for chlor-alkali production; we can exchange ideas through QQ 743370224
Sure, sharing is a joy :)
The idle ion-exchange membrane caustic soda plant in Binzhou Ocean Chemical has been unused for 2 years; Asahi Kasei’s electrolyzer has a capacity of 200,000 tons, and it is used in conjunction with the wet calcium carbide process for PVC production
The TOC in saltwater is less than 10; we do this on a daily basis, and the TOC of the auxiliary materials is also analyzed. The reason this device is expensive is its combustion tube
Your company is very generous – which company is it?
I’d like to ask everyone: what is the approximate salt concentration in our saltwater?
