Abstract: A method of controlling corrosion-related plant operation costs is provided, the method including: accumulating real-time corrosion measurements relating to a plant operation; calculating a relative degree of corrosion value that includes consideration of the real-time corrosion measurements; comparing the relative degree of corrosion value to an expected corrosion progression value associated with a predetermined target maintenance cycle; and adjusting a plant operation based on a comparison of the relative degree of corrosion value to the expected corrosion progression value associated with a predetermined target maintenance cycle. An apparatus for controlling corrosion-related plant operation costs is also provided.

Abstract: The present invention relates generally to thermal imaging systems and methods and uses therefor, and in a particular though non-limiting embodiment, to a method of detecting corrosion under insulation, as well as corrosion-related material data associated therewith. The system utilizes advanced infrared imaging video cameras to detect characteristic signatures of wet thermal traits on process equipment. Various embodiments of the invention integrate equipment, automation, and algorithms to form a method for identifying wet thermal insulation by scanning multiple locations along insulated piping, tanks, or other manufacturing equipment. Such scans can occur individually, sequentially, or simultaneously, with the results then being stored and comparatively analyzed.

Abstract: The present invention is directed to an aqueous amine resin corrosion inhibitor composition and methods of using the same for inhibiting corrosion in equipment in contact with alkanolamine, hot carbonate solutions, diglyme and/or other solvents and acid gases such as carbon dioxide, hydrogen sulfide or a mixture of the two. The inhibitor preferably relates to compositions useful for inhibiting corrosion in environments in contact with alkanolamine, hot carbonate solutions, diglyme, and/or solvent gas treating systems and acid gases, and more particularly, to an amine resin solution made by reacting sterically hindered amines such as those selected from the group consisting of alkyl diamines, alkyltriamines, amino alcohols and mixtures thereof with aldehydes, aldehyde donors, the reaction product of lower alkanolamines and lower aldehydes, and mixtures thereof.

Abstract: The subject matter of this invention is directed to compositions and compounds to minimize hydrogen charging and hydrogen induced cracking of steels comprising, in one embodiment, a propylene diamine compound and in another a carrier and propylene diamines. Preferably, the composition of that embodiment is comprised of a hydrocarbon carrier and 1,3 propylene diamines. Alternatively, compositions of the present invention may be comprised of a carrier and octadecyl trimethyl ammonium bromide. In addition, where the environment dictates, the composition of the present invention may be comprised of a carrier, at least one 1,3 propylene diamine and octadecyl trimethyl ammonium bromide.

Abstract: Certain high strength alloys lacking resistance to hydrogen embrittlement are cold worked and heat treated utilizing critical preselected conditions to result in a unique alloy having increased resistance to hydrogen embrittlement without unacceptable loss of strength. It is theorized that this unexpected improved resistance correlates with the concentration of certain elements, such as phosphorus and sulfur as impurities on the crystallographic boundary surfaces of the alloy.

Abstract: Cold-worked superalloys having improved resistance to hydrogen embrittlement are disclosed. These new superalloys are nickel- or cobalt-chromium-molybdenum superalloys and possess improved resistance to hydrogen embrittlement rendering them useful in deep sour gas wells.
