Definitions

  • the present invention relates to the use of hydrocarbyl vinyl ether homopolymers to improve the effect of cold flow improvers for fuel oil compositions.
  • the invention further relates to the use of an additive which comprises such a polymer and a customary cold flow improver for reducing the CFPP value and, if appropriate, furthermore for reducing the CFPP2 value and / or the aspiration value of a fuel oil composition.
  • Mineral oils and crude oils containing paraffinic waxes show a marked deterioration in the flow properties when the temperature is lowered.
  • the reason for this lies in the crystallization of long-chain paraffins which occur from the temperature of the cloud point (cloud point) and form large platelet-shaped wax crystals. These wax crystals have a sponge-like structure and lead to the inclusion of other fuel components in the crystal composite.
  • additives have been added to the mineral oils and crude oils in small concentrations for a long time, which often consist of a combination of nucleators with the actual cold flow improvers.
  • Nucleators are substances that generate crystal nuclei that promote the formation of tiny crystals.
  • Cold flow improvers have similar crystallization properties to the paraffins contained in mineral oil or crude oil, but prevent their growth.
  • the crude and mineral oils are wax Anti-settling additives (WASA) added to prevent the tiny crystals from sinking into the oils.
  • WASA wax Anti-settling additives
  • CFPP Cold Filter Plugging Point
  • EP-A-0 360 419 describes additives for improving the cold flow properties of fuel compositions which contain homo- or copolymers of alkyl vinyl ethers and, if appropriate, other customary cold flow improvers.
  • DE-A-2 047 448 describes an additive mixture of polyvinyl ethers with ethylene-vinyl acetate copolymers to improve the pumpability of crude oils. The use in fuel oils is not described.
  • a disadvantage of the additives of the prior art is that they sometimes do not, or only slightly, reduce the CFPP value of fuel oils.
  • the prior art does not describe any additives which have an effect on the CFPP2 and / or aspiration value of the fuel oils.
  • the object of the present invention was therefore to further improve the effect of conventional cold flow improvers.
  • the additive should improve the effect of the cold flow improvers on reducing the CFPP value of fuel oil compositions and, if appropriate, lead to a reduction or elimination of the CFPP2 values and / or to avoid aspiration effects.

Abstract

L'invention concerne l'utilisation d'homopolymères d'éther vinylique hydrocarbyle pour améliorer l'effet de promoteurs d'écoulement à froid pour des compositions de combustibles. La présente invention porte également sur l'utilisation d'un additif comportant un polymère de ce type et un promoteur d'écoulement à froid usuel pour diminuer la valeur CFPP (température limite de filtrabilité des gazoles) et réduire éventuellement aussi la valeur CFPP2 et/ou la valeur d'aspiration d'une composition de combustible.
