Abstract: A method of dispersing asphaltenes to inhibit asphaltenes precipitation and/or deposition in a hydrocarbon is disclosed. An asphaltene dispersing agent is added to the hydrocarbon. The asphaltene dispersing agent is an ester of a mono-carboxylic fatty acid and a sugar. The sugar has at least 4 hydroxyl groups and more than one of the hydroxyl groups on the sugar are reacted with the mono-carboxylic fatty acid to form the ester. A composition comprising the asphaltene dispersing agent is also disclosed.

Abstract: 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.

Abstract: A method of separating oil from a composition containing an oil and water emulsion, by adding a separation additive which is a fatty ester of alkoxylated glycerol, and performing at least one oil separation step. The method is particularly suitable for separating corn oil from stillage produced in a corn ethanol mill.
