The outlet of the sedimentation tank contains acid
Thread Content
Sampling of the product at the outlet of the sedimentation tank showed a noticeable acidic taste; the processing capacity of the reactor decreased, and the level in the sedimentation tank also dropped, but these measures had no effect. Could it be that the problem lies solely with the coalescing internals?
Not only that, but oil-in-acid is really powerful, right?
One reason could be the large volume of processing; acid in the oil may also result from leaks in the reactor tubes. Another possibility is that the level gauge is inaccurate, leading to an excess of acid. You can increase the pressure at the outlet of the sedimentation tank
There is no significant change after adjustment; it is likely a leak in the reactor tube bundle.
It was a leak in the reactor tube bundle; after the leak was sealed, there was no acid present. However, the reason for the presence of acid at the outlet of the sedimentation tank has not been clarified, and no acid was detected either after it came online
