Definitions

  • the invention relates to an additive for improving the flowability of mineral oils and mineral oil distillates containing paraffin and containing flow improvers polar on the basis of ethylene-vinyl ester copolymers and terpolymers Nitrogen compounds and ethers and / or esters as solubilizers.
  • Crude oils and middle distillates obtained by distilling crude oils such as gas oil, Diesel oil or heating oil contain different ones depending on the origin of the crude oils Amounts of n-paraffins which, when the temperature is lowered, are platelet-shaped Crystallize crystals and partially agglomerate with the inclusion of oil. This crystallization and agglomeration leads to a deterioration the flow properties of the oils or distillates, which means that during extraction, transport, Storage and / or use of mineral oils and mineral oil distillates may occur. This can happen when transporting mineral oils through pipes Crystallization phenomenon, especially in winter, to deposits on the Pipe walls, in individual cases, e.g. B. when a pipeline is at a standstill, even to it cause complete constipation.
  • the mineral oils When storing and processing the Mineral oils may also be required in winter, the mineral oils in heated To store tanks. With mineral oil distillates, it occurs as a result of crystallization if necessary, clogging of the filters in diesel engines and Firing systems, which prevents safe metering of the fuels and possibly complete interruption of fuel or Heating medium supply occurs.
  • Typical flow improvers for crude oils and middle distillates are copolymers and terpolymers of ethylene with carboxylic acid esters of vinyl alcohol.
  • Another task of flow improver additives is to disperse the failed paraffin crystals, d. H. the delay or prevention of Sedimentation of the paraffin crystals and thus the formation of a paraffin-rich Layer on the bottom of storage containers.
  • DE-A-40 19 623 discloses crystallization inhibitors for paraffins in petroleum fractions, that from fatty amines and solutions of benzoic or formic acid in methanol, Ethanol, cyclohexanol or isopropanol exist.
  • EP-A-0 104 015 discloses the use of weak organic acids, especially aromatic acids such as benzoic acid, alkylphenols and Alkarylsulfonic acids to improve the solubility of nitrogen compounds in Oil.
  • US 4,210,424 discloses the use of polymers derived from carboxylic acid esters and bearing alkyl side chains of 6 to 30 carbon atoms and / or of C 8 -C 18 alkanols as solubilizers in compositions of ethylene copolymers, paraffin waxes and nitrogen compounds.
