A gas turbine engine system includes a gas turbine engine including a compressor, combustor including a plurality of late lean fuel injectors supplied with secondary fuel; gas turbine, and wash system configured to be attached and in fluid communication with the late lean fuel injectors. The wash system includes a water source including water; first fluid source including a first fluid providing vanadium ash and vanadium deposit mitigation and removal from internal gas turbine components; a mixing chamber in communication with the water source and first fluid source; a water pump to pump the water to the mixing chamber; a first fluid pump the first fluid to the mixing chamber; a fluid line in fluid communication with the mixing chamber and late lean fuel injectors so fluid from the mixing chamber is injected into the combustor at the late lean fuel injectors while the gas turbine engine is on-line.

The invention relates to the use of a detergent composition for removing hydrophobic residues and pigments on manufacturing or packaging devices or any other hardware used for manufacturing or packaging cosmetic or pharmaceutical compositions, said detergent composition including: a non-ionic surfactant selected from among the alkoxylated fatty alcohols; a non-aromatic co-surfactant selected from among the amine oxides, alkyl sulfates and alkyl sulfonates; and an organic alkaline agent selected from among the amino alcohols, excluding monoethanolamine, the non-aromatic co-surfactant being contained in the detergent composition in an amount of from 1 to 15 wt % in relation to the total weight of the composition.

A method of cleaning an epitaxial reaction chamber in-situ is disclosed. The method may include a pre-coating step, a high temperature baking step, and a gas etching step. The method is able to remove residue buildup within the reaction chamber, which may be made of quartz.

A method, system and cleaning solutions for the ultrasonic cleaning of drill cuttings and the resulting cleaned drill solids is described. The drill cuttings are characterized by their liquid/solid composition, texture of solids and size of particulates. A cleaning solution formula having surfactant(s) and viscosity agent(s) is selected based on the characterization of drill cuttings. Drill cuttings are contacted with the selected cleaning solution and subjected to ultrasonic vibrations simultaneously for a period of treatment and vibration time. Contaminants from drill cuttings are removed to beneficial use standards and the resulting cleaned drill solids may be reused at the well site. The cleaning may occur at a well site in conjunction with drilling activity and the cleaning solution may be changed to adapt to changes in the drill mud and/or cuttings characteristics.

The present invention is directed to compositions, methods and systems for the removal of starch. The methods include: providing cleaning solution and rinsing fluid along supply line(s); connecting the supply line(s) to one or more cleaning applicators positioned to apply the cleaning solution or the rinsing fluid to one or more surfaces of a starch applicator system; and providing a controller which is able to control application of the cleaning solution and the rinsing fluid through the one or more cleaning applicators. The systems include the components described in relation to the methods. The compositions include about 5 to 15% w/w alpha amylase to break down the starch into water-soluble units; and non-ionic surfactant(s) and/or solvent(s) to react at the interface of the starch and surface it is attached to as well as liquify the resins.

Ambient moisture-activatable surface treatment powders containing persalt, positively charged phase transfer agent and alkaline pH buffering may be activatable without the addition of liquid. Some ambient moisture-activatable surface treatment powders are substantially free of bleach activators and/or chlorine. Methods of use of ambient moisture activatable powders include applying them to the surfaces to be treated.

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.

A cleaning liquid composition is provided. More particularly, a cleaning liquid composition includes a transition metal compound represented by Chemical Formula 1 (see the detailed description of the present invention); and a hydrocarbon-based solvent, and a cleaning method of a polymerization apparatus using the same.

The invention relates to cleaning deposits of various natures from metal, glass and ceramic surfaces of industrial equipment and can be used for the removal of such deposits, as metal oxides (iron, chromium, nickel, etc.), carbonate and salt deposits, asphalt-tar-paraffin deposits and deposits of an oily nature, deposits of organic and biological nature (bacterial deposits). The proposed solution for removing deposits of different natures comprises hydrogen peroxide, complexing agent, calixarene and water in the following quantitative ratio, wt. %: hydrogen peroxide, 2-90; complexing agent, 3-30; calixarene, 0.01-10; water, the balance. EFFECT: increased degree of cleaning off deposits of various natures with simultaneous reduction of solution aggressiveness to structural materials.
