On the treatment of defective sodium hydroxide water in the calcium carbide production process
Thread Content
Hello everyone. In the production of PVC via the calcium carbide method, a large amount of sodium hypochlorite is used for removing sulfur and phosphorus, which results in a significant amount of waste sodium hypochlorite water. Is there any use for this wastewater? The available chlorine in it is already very low, at around 0. About 03%. If it’s used again, can concentrated sodium hydroxide and these waste amounts of sodium hydroxide be mixed together to produce the sodium hydroxide needed in production? If there are good methods, then these wastewater can be turned into something useful, which is also a way to save energy. This post was last edited by *anglei0368 on 2007-11-23 21:01.]
In fact, the use of inferior sodium hydroxide to produce the sodium hydroxide required for manufacturing is already a well-established practice in the industry
Will using waste sodium hydroxide solution to prepare sodium hydroxide have an impact? Please advise, or could you let me know which company is doing this?

The residual sodium hypochlorite is then used as water for acetylene generators to produce acetylene. . .
