Abstract: A composition for promoting the release of bituminous materials and other adhesive materials from a substrate and methods of use thereof. More particularly, a composition comprising a silicone oil-in-water emulsion, which is stabilized by an alkoxylated polysiloxane surfactant, for use as a release agent that can be applied to a substrate, such as a truck bed, prior to use for promoting the free release of a bituminous material, such as asphalt, from the substrate.

Abstract: Water-soluble solvent compositions, including from about 10% to about 60% by weight of an aromatic ester; from about 30% to about 60% by weight of an aliphatic ester; from 0% to about 15% by weight of a co-solvent; from 0% to about 20% of one of a cyclic terpene and a terpenoid; from 0% to about 1% by weight of an odor-masking agent; and from 0% to about 20% by weight of a nonionic surfactant, for removing petroleum residue from a substrate, and methods of use thereof. The composition can further comprise water. The composition also can comprise an aqueous solution. The method for removing petroleum residue from a substrate can further comprise recycling the solvent composition by using a countercurrent separation column charged with compressed ammonia and/or carbon dioxide and a spinning band distillation column to separate the solvent composition from the petroleum residue.

Abstract: A process includes adding an effective amount of a calcium lignin sulfonate to a thickened base grease to form a lubricating grease wherein the calcium lignin sulfonate has a molecular weight of at least 10,000 g/mol; the calcium lignin sulfonate has a water content of less than about 0.5 wt %; the effective amount is from about 1 wt % to about 20 wt % based upon the weight of the lubricating grease; the thickened base grease is obtained from a grease forming process or a lubricating paste; and the lubricating grease has a water solubility below about 3 wt %, as determined by a water wash out-test.

Abstract: A method of deresinating a crude oil comprises contacting the crude oil with a carbon dioxide containing fluid, the crude oil having an initial API gravity and comprising an oil phase, resins, and asphaltenes, and wherein the carbon dioxide containing fluid enters the oil phase of the crude oil In a manner such that the resins and asphaltenes precipitate out of the crude oil such that the final API gravity of the crude oil is higher than the initial API gravity of the crude oil.

Abstract: A method of demulsifying a water-in-oil emulsion comprising an oil phase comprising asphaltenes and an aqueous phase is disclosed. The method comprises contacting a carbon dioxide containing fluid with the emulsion such that the carbon dioxide containing fluid enters the oil phase of the emulsion. The asphaltenes precipitate out of the emulsion and the emulsion destabilizes.
