A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

A lubricating oil detergent composition comprises an overbased calcium sulfonate and a low ash detergent, which low ash detergent is metal free and comprises the reaction product of an acidic organic compound such as an alkylated salicylic acid, a boron compound and an amine component.

The present invention discloses a single package additive for improving lubricity and conductivity properties of ultra-low sulfur diesel fuels. The single package additive is a reaction product of a fatty acid composition, a glycerol tricarboxylates, a polysulfone, a polyamine, an alkylated benzene sulfonic acid and a phenol derivative. More specifically, the present invention discloses a reaction product of: a fatty acid composition in the range of 60-95% wt/wt; a glycerol tricarboxylate in the range of 0.1-10.0% wt/wt; a polysulfone in the range of 0.1-5.0% wt/wt; a polyamine in the range of 0.1-5.0% wt/wt; an alkylated benzene sulfonic acid in the range of 0.1-5.0% wt/wt; and a phenol derivative in the range of 0.1-10.0% wt/wt. The present invention also discloses a single-pot process for the preparation of said reaction product.

Oxidized disulfide oil (ODSO) compounds, derived from by-product disulfide oil (DSO) compounds from the MEROX process, are effective as lubricity additives for transportation fuels. Significant increases in lubricity of ultra-low sulfur fuels as measured by the WSD test were observed with addition of ODSO compounds in the range of from 0.1 ppmw to 10 ppmw. This use of ODSO compounds as lubricity additives converts an otherwise DSO waste oil product into a valuable commodity that has utility in improving lubricity properties of transportation fuels.

Disulfide oil (DSO) compounds recovered as a by-product of the mercaptan oxidation of a hydrocarbon refinery feedstock and their oxidized derivatives, oxidized disulfide oils (ODSO) are effective as a diluent to lower the viscosity and thereby improve the pipeline transportation properties of heavy oils, and particularly of wellhead crude oil. The use of the DSO and/or ODSO compounds as diluents converts an otherwise extremely low value or waste oil product into a valuable commodity that has utility in improving the transportation properties of heavy oils, particularly in oil field pipeline applications.
