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.

A freshening composition and method of jetting a freshening composition from a microfluidic device are provided. The composition includes greater than 5 wt. % of solubilizing materials that are liquid at 20 C. Each of the solubilizing materials have a Hansen polarity parameter (p) of greater than 5 MPa0.5; a Hansen hydrogen-bonding parameter (h) of greater than 9 MPa0.5; and a vapor pressure of less than 267 Pa. The method includes heating the freshening composition with a thermal actuator and atomizing the heated composition from a nozzle in a direction that is from 0 degrees to 90 degrees from the direction of gravitational force.

Alkaline sprayable aqueous compositions for cleaning, sanitizing and disinfecting are disclosed. In particular, the sprayable compositions include an alkali soluble emulsion polymer, an alkalinity source, a foaming agent, and water. Beneficially, the sprayable cleaning compositions have reduced misting and are environmentally safe for users to apply. Further the compositions exhibit less running on non-horizontal surfaces than acrylamide-based compositions.

The present application provides liquefied-gas aerosol compositions which are useful in for preventing incidents of inhalation abuse. The compositions described herein comprise, for example, i) a propellant component comprising one or more hydrohaloolefins; and ii) one or more bitterants.

By fluorinating 1,2,3,3-tetrachloro-1-propene (1230xd) using hydrogen fluoride as a fluorinating agent, an efficient method for producing 1,2-dichloro-3,3-difluoro-1-propene (1232xd) is provided. Through this composition including 1232xd, there are also provided an environmentally friendly composition having excellent ability to dissolve various organic matters, a method for cleaning an article using the composition, a method for producing a lubricant solution using the composition, and a method for producing a component provided with a lubricant coating film.

A solvent composition has an oxygenated solvent and a siloxane solvent. In one embodiment, the oxygenated solvent is propylene glycol methyl ether and the siloxane solvent is hexamethyldisiloxane or octamethyltrisiloxane. In another embodiment, the solvent composition is an azeotrope of propylene glycol n-butyl ether and decamethyltetrasiloxane. The siloxane solvent can be used in any situation where one desires to remove a silicone deposit, e.g., conformal coatings, adhesives, sealants, greases, heat transfer fluids, paints, oils, etc.

A cleaning liquid includes a static liquid (13), a second fine gas bubble group (26) contained in the static liquid (13) and formed by a gas at a first temperature, a dynamic liquid (22) that flows toward an object to be cleaned (W) that is held in the static liquid (13), and a second fine gas bubble group (26) formed by a gas at a second temperature different from the first temperature, the second fine gas bubble group (26) being entrapped by a flow of the dynamic liquid (22) and flowing toward the object to be cleaned (W). This makes it possible to provide a cleaning liquid that exhibits a cleaning effect remarkably better than ever before.

A miscible solvent system and method for making same having a composition between about 10 to about 90 weight percent PCBTF and between about 10 to about 90 weight percent fluorinated solvent. The miscible solvent system may be combined with boron nitride powder to create a bulk paint system. Further the miscible solvent system may be combined with a propellant to create an aerosol system. The miscible solvent system, bulk paint system, and aerosol system may be nonflammable or flammable and contain VOCs or be VOC free.

A device for rapidly sanitizing a surface is described. The device has an enclosure having an opening adapted to insert a surface, and an interior; a liquid nitric oxide solution applicator; and an absorbent material. The liquid nitric oxide solution applicator is in fluid communication with the interior of the enclosure and is adapted to apply liquid nitric oxide solution onto the surface when the surface is positioned within the enclosure. A method of rapidly sanitizing a surface is described. The devices and methods provided herein may be implemented to sanitize the surface of any body part or item that may be placed within the device. An infectious agent on the surface may be killed; i.e., the surface is disinfected. Non-limiting applications of the devices and methods include preventing nosocomial infections or food contamination, sanitizing household items, and implementing sanitizing procedures to comply with FDA Good Manufacturing Practices.
