Prepare sodium carbonate using dechlorinated dilute brine
Thread Content
This post was last edited by sunjl1981 on January 6, 2013, at 23:30. The sodium carbonate pipelines in my company are prone to blockages, which affects production stability. Personally, I believe this is due to the presence of calcium and magnesium in the tap water (analysis shows 70 mg/L). If we switch to demineralized brine after dechlorination, the calcium and magnesium content would be significantly reduced. This should resolve the pipeline blockage issue and also reduce sodium carbonate consumption. However, the initial equipment investment would be quite high. Is this a feasible solution? Dear fellow seafarers, please help analyze this. ,,, -
Isn’t it sufficient to use pure water? I also don’t think that clogged pipes are necessarily caused by what you mentioned; sodium carbonate can also crystallize. In my opinion, this is simply a bad idea
The consumption of pure water is quite high. After dechlorination, the concentration of the brine reaches 210 g/L, and its temperature is around 70°C. In winter, it eliminates the need for steam used in mixing sodium carbonate. What does the management believe to be the reason for the crystallization in the sodium carbonate pipelines?
What’s the concentration you prepared? If you have trouble controlling the free chlorine levels, what material should be used for the sodium carbonate pipes and pumps? It is recommended that you add some water after each preparation of sodium carbonate to flush out the pipes. How much purified water would this consume? This process needs to be done once a day.
