Filed:

Jan 8, 2016

Appl. No.:

15/541939

Inventors:

- Edison NJ, US
Craig Michael Sungail - Chadds Ford PA, US
Xin Chen - Hockessin DE, US

Assignee:

Croda, Inc. - Edison NJ

International Classification:

C11B 1/10
B01D 17/04
C11B 13/00
C12F 3/10

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.

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.

International Classification:

C08K 3/04
C07C 237/12
C08K 5/20

Abstract:

A composition comprising at least one particulate inorganic or organic compound, and a dispersant, said dispersant comprising a residue of a dimer fatty acid and/or trimer fatty acid having at least one carboxylic acid group derivatised to provide a terminal secondary or tertiary amine. The dispersant may be formed by reaction of a dimer fatty acid and/or trimer fatty acid and a secondary or tertiary amine comprising compound. The invention also includes the use of the dispersant for dispersing a particulate inorganic or organic compound in a composition.
