Excessive cold-high-purity ferric ions
Thread Content
We have a 200,000-ton catalytic hydrogenation reforming unit here, and recently the level of ferric ions has often been above the acceptable limit, while the pH value is normal. Could experts tell me what might be causing this?

I agree with the view above: the impurities in catalytic diesel generate acidic substances during the hydrogenation process, which can cause corrosion to the equipment through which it flows; as a result, the iron ion level becomes excessive. There is very little acidic corrosive medium, and the pH value shows no significant change.
