Removal of naphthenic acids in crude oils and distillates |
| abstract |
The instant invention is directed to a process for extracting organic acids from a starting crude oil comprising the steps of: (a) treating the starting crude oil containing naphthenic acids with an amount of an alkoxylated amine and water under conditions and for a time and at a temperature sufficient to form a water-in-oil emulsion of amine salt wherein said alkoxylated amine is selected from the group consisting of alkoxylated amines having the formulae (A) where m+n = 5 to 50 and R = linear or branched alkyl group of C8 to C20, and (B) H-(OCH2CH2)y-(CH2CHCH3O)p-{NHCH2CH2NH}x-(CH2CH2O)z-(CH2CHCH3O)q-H where x = 1 to 3 and y+z = 2 to 6, and wherein p+q = 0 to 15, mixtures of formula (A) and mixtures of formula (B); wherein said starting crude oil is selected from the group consisting of crude oils, crude oil blends, and crude oil distillates; and (b) separating said emulsion of step (a) into a plurality of layers, wherein one of such layers contains a treated crude oil having decreased amounts of organic acids; (c) recovering said layer of step (b) containing said treated crude oil having a decreased amount of organic acid and layers containing water and alkoxylated amine salt. |
