摘要： A system and method for a metal sequestration composition comprising combining a galactaric salt or galactaric acid with a metalloid oxyanion, and an alkali compound. The system and method enable the production of a metal sequestration composition that either alone or in combination with other functional components (e.g., surfactants, solvents, pH modifiers) provide water treatment or cleaning compositions.

摘要： An aqueous cleaning solution for removing rouging deposits on media-contacted surfaces of stainless steels comprises a first component and a second component. The first component is an alkali sulfite and the second component is an alkali formate, wherein the concentrations thereof are adjusted in such manner that formate is present in a molar ratio of 1.5 to 4.2 relative to sulfite, and that the pH value of the cleaning solution is 4.0 to 4.8. For preparing the aqueous cleaning solution, an aqueous solution of an alkali hydroxide is provided initially, thereafter a first amount of concentrated aqueous formic acid is admixed in an excess in such manner that a pH value of 3.5 to 4.5 is established, then a second amount of solid alkali sulfite is admixed in accordance with the sulfite concentration to be established, thus resulting in a pH value of 5.5 to 6.5, and finally a third amount of concentrated aqueous formic acid is admixed until a pH value of 4.0 to 4.8 is attained.

摘要： Embodiments of the present disclosure generally relate to methods for refurbishing aerospace components by removing corrosion and depositing protective coatings. In one or more embodiments, a method of refurbishing an aerospace component includes exposing the aerospace component containing corrosion to an aqueous cleaning solution. The aerospace component contains a nickel superalloy, an aluminide layer disposed on the nickel superalloy, and an aluminum oxide layer disposed on the aluminide layer. The method includes removing the corrosion from a portion of the aluminum oxide layer with the aqueous cleaning solution to reveal the aluminum oxide layer, then exposing the aluminum oxide layer to a post-rinse, and forming a protective coating on the aluminum oxide layer.

摘要： Phosphorus-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces. The detergent compositions are used with a sanitizer to employ the phosphorus-free detergent compositions for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the phosphorus-free detergent compositions are also provided.

摘要： A cleaning liquid having an excellent corrosion inhibition function, and a method for manufacturing the same. The cleaning liquid contains alkanol hydroxyamine represented by general formula (1), and a basic compound other than the alkanol hydroxyamine. In the formula, Ra1 and Ra2 each independently represents a C1-C10 alkyl group having one to three hydroxy groups, or a hydrogen atom, and Ra1 and Ra2 are not simultaneously a hydrogen atom.

摘要： Compounds of biodegradable surfactants useful for optimizing the separation of impurities typical of hydrocarbons, and designed to intervene and stabilize the molecular structure of crude oil, with no significant alterations of the crude's intrinsic composition are disclosed. The biodegradable surfactants compounds coexist with a non-ionic surfactant and an organic mix in emulsion form with the purpose of isolating crude from the pipeline, reduce friction to improve crude flow and to enter the crude macromolecule to modify the hydrocarbon chain to reduce its density and thus its viscosity; including compounds of biodegradable surfactants that comprise sodium hydroxide 1N, potassium chloride, sulphonic acid, dodecanoic acid, nonylphenol, terpene-1 and water, preferably hard water.
