摘要： An aqueous acid composition that may be used, for example, in a matrix acidizing treatment can include an acid, a polymeric acid corrosion inhibitor, and an acid corrosion inhibitor intensifier. The acid corrosion inhibitor can include iodide ions and metal ions, with the metal ions being one or more of copper, silver, bismuth, or antimony. The molar ratio of metal ions to iodide ions can be 1:X, where X is greater than or equal to 2. The polymer of the polymeric acid corrosion inhibitor can have a molecular weight less than 100,000 g/mol.

摘要： A corrosion inhibiting compound with a general structure A-B or A-X-B for inhibition of corrosion of steel in acidic solution. A comprises a heterocyclic ring system having a plurality of cyclic Carbon atoms and at least one cyclic Nitrogen atom, wherein the at least one cyclic Nitrogen atom is neutral under neutral conditions and protonatable under acidic conditions. B comprises at least two unsaturated Carbon atoms. B may comprise a ring system or a polymerisable group.

摘要： A method for measuring a thickness of a deposit layer on a metal or alloy substrate using an X-ray fluorescence (XRF) spectrometer, where the deposit layer includes scale deposits or corrosion products. As part of the method, an elemental composition of the deposit layer or the metal or alloy substrate is measured using the XRF spectrometer. The thickness of the deposit layer is obtained from the elemental composition using a calibration relationship between deposit layer thicknesses and corresponding elemental compositions of the deposit layer or the metal/alloy substrate. The method can be applied to determine the rate of deposit layer formation and evaluate the effectiveness of a treatment.

摘要： Corrosion of steel in acidic solution is inhibited using a mixture of a compound in which a plurality of heterocyclic aromatic groups with a quaternary nitrogen atom are connected together, such as by a linking group which may be covalently attached to the quaternary nitrogen atoms of the aromatic heterocyclic rings, and a polarizable adsorption-intensifying anion.
