An anti-static fuel additive composition and method for using the composition to reduce or prevent buildup of electrostatic charge is described. The anti-static fuel additive composition comprises a polysulfone and a copolymer derived from reaction of an alkanolamine and a hydrocarbyl-substituted 4-membered to 7-memebered ring anhydride; for example, a hydrocarbyl-substituted succinic anhydride, a hydrocarbyl-substituted maleic anhydride, a hydrocarbyl-substituted phthalic anhydride, or a combination thereof.

This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are asphalt-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

A method and an industrial plant for separating a waste material comprises at least one metal and at least one organic material. A separated fraction of the waste material is provisioned which is isolated from the waste material in the course of a mechanical preparation operation. The separated fraction comprises briquettes produced from the waste material, and optionally a coarse fraction of the waste material or of another waste material. A reactor is charged with the separated fraction and gas containing oxygen is introduced into the reactor and the separated fraction is combusted in an incomplete combustion process. The separated fraction is melted into a liquid slag phase and into a liquid metal-containing phase. The slag phase and/or the metal-containing phase are poured off from the reactor.

A method of inhibiting asphaltene precipitation and/or deposition in a hydrocarbon, preferably crude oil, by adding to the hydrocarbon a polyester asphaltene dispersing agent which is the reaction product of an alk(en)yl substituted succinic anhydride wherein the average number of succinic groups per alk(en)yl group is less than 2.0, and at least one polyol.

The present embodiments describe a method to reduce vanadium corrosion in a gas turbine by adding an oleophilic corrosion inhibitor into a combustion fuel, in which the oleophilic corrosion inhibitor comprises carbon black support particles and magnesium bonded to the carbon black support particles. The carbon black support particles comprise a particle size less than 40 nanometer (nm), and oxygen content less than 1 weight percent (wt %), and a surface area of at least 50 square meters per gram (m.sup.2/gram).
