Abstract: Petroleum distillates with improved properties contain minor amts. of a conventional ethylene-based flow improver (I) and a copolymer (II) comprising 10-95 mol.% of one or more 1-26C alkyl (meth)acrylates and 5-90 mol.% of one or more ethylenically unsatd. dicarboxylic acids or anhydrides, post-reacted with one or more primary or sec. amines to form the corresp. monoamide or amide/ammonium salt. (I):(II) wt. ratio is 40-95:60-5. - Pref. (I) is a copolymer of ethylene with vinyl acetate, vinyl propionate or ethylhexyl acrylate. (II) is a copolymer of 40-95% lauryl acrylate or 8-18C alkyl acrylate and 5-60% maleic anhydride, post-reacted with di(hydrogenated tallow) amine (DHTA), behenylamine or n-octadecylamine. (II) is opt. grafted onto (I). The distillates contain 50-5,000 ppm (I)+(II).

Abstract: Oxalkylated polyamines containing amide groups which are suitable as demulsifiers for crude oil and are obtainable by condensation of dicarboxylic acids having 3 to 20 carbon atoms or functional derivatives thereof with polyalkylene-polyamines having at least 2 carbon atoms and at least 2 amino groups and reacting the reaction product with a total of from 1 to 200 mol/mol of ethylene oxide and/or propylene oxide and/or 1,2-butylene oxide.

Abstract: The subject invention relates to compositions which inhibit the corrosion caused by CO2 and H2S in the transport and storage of crude oils, which are generally water-in-oil, in particular salt-water-in-oil emulsions. The corrosion inhibitors are mixtures of certain imidazoline or tetrahydropyrimidine derivatives, precursors thereof, or their complexes with sulfur and certain maleinamidic acids.

IPC: C09K3/18
Abstract: Title compsn. contains 30-70 wt.% of propylene glycol, 15-40 wt.% of urea and 15-60 wt.% of water, opt. with addition of a small amt. of a corrosion inhibitor. The addition of water accelerates thawing. The mixt. is non-flammable under operating conditions.
