How to deal with alkaline and salty stains on the ground?

Recently, due to shift work, I’ve been annoyed by the salt and alkali stains on the floor; at work I have to use a hose to clean them, while also being careful about electrical safety, making sure that the oil tank doesn’t get flooded, and avoiding using high-temperature pumps for cleaning. Yet the salt and alkali stains reappear the next day – it’s really frustrating! Do anyone have any good suggestions? This post was last edited by sister on 2009-3-2 19:33 ] # ， ， &
1. The fundamental approach is to identify leaks. 2. Use waste acid and waste alkali for neutralization
Cement floors seem to require more work… May I ask the moderator about the staffing and production capacity for ion membrane electrolysis, secondary brine treatment, dechlorination, and ion membrane evaporation (if any).
Yes, the real solution is to seal the leaks; flushing is only a temporary fix.
Based on 150,000 tons of caustic soda: Ion membrane electrolysis: 2 people; Secondary brine: none (combined with electrolysis); Dechlorination: none (combined with electrolysis); Ion membrane evaporation: 2 people using Swiss Bot technology. For high-purity hydrochloric acid: 2 people. For rectification DCS and inspections: 1 person. In addition, there is a shift leader; each position requires one DCS operator and one inspector.

Leakage is inevitable in chemical production! It’s unavoidable. To keep the floor clean, it’s best to clean it regularly; otherwise, once acids or bases seep into the floor, it will be difficult to clean it~~
For salt stains, they can be removed by rinsing with plenty of water. Alkaline stains can also be washed away with water, but avoid using acids to neutralize them, as acids are even more corrosive to floors than alkalis. The key is to conduct regular inspections, seal any leaks promptly; if it’s not possible to seal them, use containers to hold the liquid until it can be dealt with during a major repair.
It’s a miracle that the operator didn’t get exhausted to death!
There’s nothing much to do during normal driving operations; it’s sufficient to monitor all the relevant data. Usually, the most that needs to be done is cleaning, taking samples, and carrying out inspections. If there is any issue, the managers and technical staff will come and handle it right away. This is the ion membrane workshop, which features a high degree of automation; many processes are carried out automatically, and there are also historical records available.

Out of curiosity, what about driving? There are even fewer people who are as stingy as those in our well-known private enterprises; I really admire that
I guess you’ve never been in a chlor-alkali plant before; this is just the electrolysis workshop. There are other workshops as well, such as those for chlorine compression and primary brine. It’s very convenient to operate this equipment – first start up the circulation system, have one person gradually increase the current, and the DCS will take care of controlling all the parameters
It is said that 5S management strictly prohibits using water to clean the floors – can chlor-alkali enterprises do this?
It’s really annoying; rinse it with water promptly (hot water is better)； Alkaline soaking can also be rinsed off with water; if that doesn’t work, apply diluted hydrochloric acid. In short, conduct more inspections; seal any leaks as soon as they are detected. If it’s not possible to seal them, use containers to hold the liquid temporarily, and address the issue when the opportunity arises.
Our method is to use a mop dipped in a small amount of used engine oil for application, and it works effectively for a long time. This post was last edited by haining on 2009-3-10 10:33.]
It’s the same with us; once the water washes over it, it returns to that state. The key is to stop the leaks
The fundamental solution is to focus on equipment maintenance and management in order to completely eliminate any leaks; this is definitely achievable.:victory:
Clarify the source of the base and salt. Is it a pump, a pipe, or equipment leakage? There are few foreigners here, but no leaks; the workers just come to clean and wipe down the equipment. It is recommended to use a mechanical seal without cooling water for the pump.
