Definitions

  • the invention relates to the use of alpha-olefin, vinyl ester and alpha, beta-unsaturated carboxylic acid ester copolymers as additives for improving the cold-running performance of fuels and lubricants as well as fuel oils and lubricants. packages containing these copolymers.
  • the hydrocarbon compositions especially those based on middle distillate type containing paraffin waxes, such as for example diesel fuels and heating fuel oils have a significant decrease in their flow properties. It is well known that the crystallization of paraffins is a limiting factor for the use of middle distillates. Also, it is important to prepare diesel fuels adapted to the temperatures at which they will be used in motorized vehicles, that is to say to the surrounding climate. Generally, cold operability of fuels at -10 ° C is sufficient in many hot or temperate countries. But in cold climate countries, such as the Scandinavian countries, Canada, and Northeast Asian countries, fuel usage temperatures well below -20 ° C can be achieved. It is the same for domestic fuel stored outside buildings (houses, buildings, ).
  • paraffins are crystallized at the bottom of the tank, they can be driven to start in the fuel system and particularly clog filters and prefilters arranged upstream of the injection systems (pump and injectors). Similarly for the storage of domestic fuel oils, paraffins precipitate at the bottom of the tank and can be driven and obstruct the pipes upstream of the pump and the boiler supply system (nozzle and filter). It is obvious that the presence of solids, such as paraffin crystals, prevents the normal circulation of the middle distillate.
  • CFI cold flow improvers
