What are the reasons for excessive iron ions in the circulating water of refineries? What are some good methods to identify leakage points upstream?
Are they iron ions resulting from pipe corrosion?
The iron ion level is too high; if there is no problem with the raw water, then the corrosion rate must also be above the normal level.
If the iron ion level is too high during normal operation, it is first necessary to increase discharge and water addition, and then ensure that corrosion inhibitors and disinfectants are used in sufficient quantities. Check whether any other pipes that were unused before have been reactivated. Corrosion of the pipes due to long-term disuse. Then, when it was turned on again, the rust in the pipes flowed along with the water to various parts of the system. Discharge and water replenishment: Add chemicals as usual, and also add bactericides.
