Abstract: A method of inverse emulsion polymerisation using an oil phase comprising a hydrocarbon oil obtainable from a gas to liquids process (a GTL oil) is described, in addition to an emulsion comprising a GTL oil and the use of a reaction product of an alk(en)yl substituted succinic anhydride and an amino alcohol to emulsify the emulsion.

Abstract: A process for making a surfactant composition is disclosed. In the process, a mixture comprising a sugar alcohol and fatty is formed. The mixture contains less than 5% by weight of water based on the total weight of the mixture. The mixture is reacted with an alkylene oxide to make a surfactant composition containing an alkoxylated sugar alcohol fatty acid ester and a polyalkylene glycol fatty acid ester. A surfactant composition and use of the surfactant composition to separate an oil phase and/or an aqueous phase from an emulsion is also disclosed.

Abstract: Provided is a method of dispersing asphaltenes to inhibit asphaltene precipitation and/or deposition in a hydrocarbon. The method includes adding to the hydrocarbon an asphaltene dispersing agent which is an ester of a mono-carboxylic fatty acid and a sugar. The sugar has at least 4 hydroxyl groups. In addition, more than one of the hydroxyl groups on the sugar are reacted with the mono-carboxylic fatty acid to form the ester.

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 mixture of a fatty ester of an alkoxylated polyol and 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.
