Abstract (en)
[origin: EP0084411A1] Hydrocarbon oils may be cleaned from hard, inorganic surfaces by the application of an aqueous solution (e.g. sea water) containing from 0.1 to 10% by weight of a mixture of (A) 5 to 95% by weight of an alkoxylated, alcohol, carboxylic acid, alkyl phenol, alkylamine or nonionic phosphate ester, having in each case at least one alkyl group with from 6 to 22 carbon atoms and from 1 to 20 ethyleneoxy and/or propyleneoxy groups, with (B) from 95% to 5% by weight of at least one alkenyl or alkyl mono- or di-ethanolamide or an ethoxylated or polyethoxylated alkenyl or alkyl mono- or di-ethanolamide wherein the alkyl or alkenyl group has from 5 to 17 carbon atoms and having 1 to 12 total ethoxy groups. The method is of particular value for cleaning drilling oil from rock cuttings in offshore drilling operations.
