Why does the alkali in the LPG C4 alkaline washing tank crystallize?
Thread Content
The waste alkali pipeline is blocked. It can’t be opened even with steam.
This is related to the concentration of the alkaline solution and the temperature of the alkali washing; it is important to pay attention to this. It’s not easy to deal with once it appears; just remove the flange and handle it gradually.
Using steam doesn’t work well; in fact, there are better ways to handle it

It’s not clear what the optimal concentration of the alkali solution in the alkaline cleaning tank should be; some information indicates that if the concentration is too high, sodium sulfite will be formed, which can clog the mixer and make it difficult to clean Therefore, it is crucial to control the low concentration of the alkaline solution and the appropriate alkali washing temperature. To achieve a good cleaning effect, it is not advisable to simply increase the concentration of the alkaline solution.
Make sure the temperature isn’t too low and the concentration isn’t too high; change the alkaline solution frequently
May I ask if the crystalline substance is sodium carbonate or sodium sulfite? What kind of analysis should be performed on the base to determine its composition?
The solubility of sodium sulfite in water is 12% at 0 degrees, 16% at 10 degrees, 21% at 20 degrees, 26% at 30 degrees, 27% at 40 degrees, 26% at 50 degrees, 25% at 60 degrees, 21% at 100 degrees, and 19% at 110 degrees.

The temperature is below the saturation temperature of the base
