<p>This invention relates to a fuel oil composition having improved cold-flow properties and comprising a cold flow additive and streams from various pipestills of a petroleum crude refinery process: a) a relatively heavy fraction from a catalytically cracked heavy gasoil in turn derived from an atmospheric or vacuum pipestill, said fraction having a boiling range of 170 to 380 °C in an amount of 3 to 20 % by weight and b) a gasoil product from an atmospheric pipestill, said product having a boiling range of 225 to 360 °C in an amount of 30-50 % by weight, whereby components (a) and/or (b) is at least partially replaced by at least one relatively light naphtha fraction (c) from the atmospheric or vacuum pipestills, fraction (c) having a boiling range of 130 to 235 °C and being present in an amount of 3 to 20 % by weight.</p> |
