System and methods for selective cleaning of turbine engine components

System for selectively contacting a cleaning composition with a surface of a turbine engine component is presented. The system includes a cleaning apparatus and a manifold assembly. The cleaning apparatus includes an upper portion and a lower portion defining a cleaning chamber configured to allow selective contact between the cleaning composition and a surface of the first portion of the turbine engine component. The upper portion includes a plurality of fill holes in fluid communication with the cleaning chamber, and the lower portion includes a plurality of drain holes in fluid communication with the cleaning chamber. The manifold assembly is configured to selectively circulate the cleaning composition from a reservoir to the cleaning chamber via the plurality of fill holes, and recirculate the cleaning composition from the cleaning chamber to the reservoir via the plurality of drain holes. Methods for selectively cleaning a turbine engine component is also presented.

Galactarate based metal sequestration composition
11560529 · 2023-01-24 · ·

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.

Ferrate compositions for surface disinfection

Methods for disinfecting a surface are provided which include contacting a surface with a solution comprising Fe(VI)O.sub.4.sup.2−, thereby disinfecting the surfaces. In some cases, the surface to be contacted with the solution is in a space suitable for human occupancy and the surface is arranged in the ambient of the space. In addition, solutions comprising Fe(VI)O.sub.4.sup.2− are provided. The solutions may additionally include a hypohalite salt and a surfactant.

CLEANING COMPOSITIONS CONTAINING GUM AND METHODS OF USE THEREWITH

The disclosure provides cleaning compositions including at least one acid, at least one carbonate salt, at least one gum, at least one acid salt, and, optionally, at least one chelating agent. When exposed to an aqueous medium, the cleaning compositions may produce carbon dioxide. These cleaning compositions find use, for example, in cleaning textile fibers, such as carpets, drapery, upholstery, and the like. The disclosure provides methods of cleaning soiled textile fibers with a cleaning composition including gum arabic, at least one acid, and at least one carbonate salt.

Method of regenerating member and method of seawater desalination

This method, for regenerating a member used in a device that treats seawater, involves a cleaning step for removing deposits from the member. In the cleaning step, a first chemical solution containing an acid other than hydroxydicarboxylic acid and a second chemical solution containing hydrogen peroxide, a heavy metal compound and hydroxydicarboxylic acid are used.

Removal of paint from porous, smooth, and mineralogically fragile surfaces

Compositions and methods of the invention are directed to the removal of solid films, and particularly paint layers, from substrates, and particularly smooth, porous, and/or mineralogically fragile substrates such as sandstone. The compositions include cooked aqueous solutions of starch. The compositions can advantageously remove paints and other unwanted solid films from these and other substrates without damaging the substrate itself.

Aqueous composition and cleaning method using same

An aqueous composition includes (A) from 0.001 to 20 mass % of one or more kinds of fluorine-containing compounds selected from tetrafluoroboric acid, hexafluorosilicic acid, hexafluoroaluminic acid, hexafluorotitanic acid and a salt thereof, with respect to the total amount of the aqueous composition; and (B) from 0.0001 to 10 mass % of one or more kinds of compounds selected from a C.sub.4-13 alkylphosphonic acid, a C.sub.4-13 alkylphosphonate ester, a C.sub.4-13 alkyl phosphate and a salt thereof, with respect to the total amount of the aqueous composition.
