Summary: | Sulfonated alkylphenol is added to crude oil at 5 to 200 ppm to inhibit naphthenic acid corrosion of ferrous metal process piping and equipment in contact with the crude oil at naphthenic acid corrosion conditions. There are disclosed corrosion-inhibited hydrocarbon fluids, an improvement in hot hydrocarbon processing with sulfonated alkylphenol, a method for inhibiting naphthenic acid corrosion therewith, and a method for catalytically processing hydrocarbons with sulfonated alkylphenol to avoid catalyst poisoning by iron compounds. |
