Abstract:
C5- to C15-alkanols are suitable for improving the defoamer action of a silicon-containing anti-foam in fuel oils, especially in biofuel oils, which comprise at least one additive with detergent action. Such alkanols are used in additive concentrates which also comprise aromatic hydrocarbons or hydrocarbon mixtures having a boiling point of 100 to 250° C. or C5- to C12-alkyl nitrates, and also silicon-containing antifoams, additives with detergent action and optionally commercial dehazers.
Abstract:
Use of a Fischer-Tropsch derived fuel in a fuel composition is disclosed, for the purpose of reducing catalyst degradation in a catalytically driven or catalyst containing system which is running on, or is to be run on, the composition or its products, wherein the Fischer-Tropsch derived fuel is used to reduce the level of silicon in the fuel composition, such as by reducing the concentration of silicon-containing antifoaming additive(s) in the fuel composition. It may also be used to reduce loss of efficiency of fuel atomization and/or combustion, and/or to reduce build up of silicon deposits, in a fuel consuming system which is running on, or is to be run on, the fuel composition.

Abstract:
In a method for effectively depositing an anti-corrosion and anti-oxidation material, such as silicon dioxide, on high-temperature components of a gas turbine, including blades rotating at a high speed during the operation of the gas turbine, an organic compound including a metal ingredient, such as silicon, is added to a fuel for the gas turbine, such as LNG, diesel or kerosene, or the organic compound is sprayed into combustion air so that the organic compound can burn together with the fuel, in order to improve the durability of the high-temperature components. Silicon dioxide, produced by burning a silicon organic compound together with the fuel, is uniformly deposited on all the high-temperature components of the gas turbine, which are exposed to the combustion gas of a high temperature, thus forming an anti-corrosion and anti-oxidation coating layer of a thickness of several to several tens of μm on the high-temperature components during the operation of the gas turbine.
Abstract:
The invention relates to a method for separating emulsions of oil and water, the method comprising incorporating a demulsifying-effective amount of a silicone demulsifier into an emulsion comprising an oil phase and an aqueous phase, the silicone demulsifier having a molecular structure comprising a polysiloxane backbone of at least two siloxane units covalently bound to (i) one or more alkylene oxide groups comprising one or more alkylene oxide units independently having one to five carbon atoms, and (ii) one or more oxirane-containing and/or oxetane-containing groups, wherein said oxirane or oxetane is optionally ring-opened by reaction with a chemical or group capable of ring-opening an oxirane or oxetane ring, respectively, and wherein a solid filler is substantially excluded from the silicone demulsifier and emulsion. The invention also relates to compositions containing the above-described demulsifier and the water and oil phases of an emulsion.
Abstract:
A process for removal of a pollutant from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that removes the pollutants from the flue gas.
