What is the color of the quench water? ?
Thread Content
Why is the quenching water dark green in color? It’s pretty much the same as black. Replacement doesn’t have much effect either. Does anyone with experience in this area have anything to share? Thank you. .
Check whether there are any leaks in your heat exchangers
By checking the turbidity of the water, if it becomes turbid, sulfur must have been produced inside the quench tower.
There is a large amount of sulfur dioxide inside the quench tower; when it comes into contact with the quench water, acidic water is formed, which gives the water a darker color. Check the operating conditions of the hydrogenation reactors in the front section. I’m not aware of your exhaust gas treatment process; if there are absorption towers, then check the solvent flow process (series solvent use?). lol
2# wang*nhua77020 Isn’t the heat exchanger meant for circulating water? Could it be dark green in color? Then the liquid level in our quench tower is fine. If it’s due to the heat exchanger. There must be a problem with the liquid level! ! !
3# hnlh Water is dark green. There are no impurities inside!
4# MANAI Thank you. Let’s adjust and investigate it
How can there be leakage? Even if there were an absorption tower, it’s impossible for anything to leak through from it! ! I think it’s likely that the quench tower is a bit dirty. What’s the pH level? It’s because of the severe corrosion!
It is possible to analyze the iron ion content in the water; if it is not high, it means that there are solid impurities in the water with very small particle sizes
I’m not sure how the reduction furnaces are performing – could it be due to a lack of hydrogen or a low reaction temperature? It’s also necessary to analyze the quench water to determine what components are present in it
Dark green~ It’s probably due to ferrous ions! ! ! Take a sample for testing to check the ferric ion content... It might be due to corrosion...
