Issues regarding the dosing of corrosion inhibitors in catalytic cracking units
Thread Content
Is the amount of corrosion inhibitor added adjusted strictly based on the quality of the acidic water?
We make adjustments based on the level of iron ions in the acidic water; the concentration of iron ions should not exceed 3 milligrams per liter
Is the filling amount adjusted frequently? What are the solutions to the high concentration of acidic iron ions in the reflux tank at the top of the stabilizer in an absorption stabilization system?
We basically make no adjustments. Currently, the injection rate is 13 ppm. Are the levels of ferric ions in the acidic water from your condensate tanks and crude gasoline tanks high?
It’s not high; it’s only the water level in the reflux tank at the top of the stabilizer that is high
