Abstract: The present invention is directed to the use of a solution of a percarbonate compound to prevent fouling during the basic washing of hydrocarbons containing oxygenated compounds. More specifically, oxygenated compounds such as carbonyl containing organics have a tendency to polymerize, producing fouling elements when such are contained in hydrocarbons being washed with basic materials. Solutions of percarbonate compounds are quite effective in reducing the fouling tendencies due to these specific mechanisms.

Abstract: Reaction products of polyalkenyl succinic anhydrides with aromatic secondary amines, then further reacted with aminoalcohols are used as effective antifoulants in liquid hydrocarbonaceous mediums, such as crude oils and gas oils, during processing of such liquids at elevated temperatures. The reaction products are formed via a two-step reaction in which a polyalkenylsuccinic anhydride precursor is reacted with an aromatic secondary amine to form polyalkenylsuccinamide intermediate which, in turn, is reacted with an aminoalcohol.

Abstract: A composition and method for controlling corrosion of steel in aqueous systems such as cooling and boiler systems. The combination of a nonionic surfactant and an anionic oxygen containing group such as one or more alkali metal salts of borate, molybdate and nitrate/nitrite provide improved corrosion inhibition of steel in aqueous systems. The magnetite layers formed in the presence of this combination exhibit decreased porosity and increased corrosion resistance to acidic solutions. This combination also inhibits entry of hydrogen into steel when exposed to acidic solutions thereby inhibiting hydrogen embrittlement. The preferred nonionic surfactant is phenol/polyethylene oxide nonionic surfactant and the preferred alkali metal salt is Na.sub.2 MoO.sub.4.
