The reason why the solidification of diesel at lower temperatures is due to a certain amount of diesel wax (ie n-alkanes) diesel PPD, when the temperature is lowered, the wax will gradually precipitate and form wax crystals. With further lowering the temperature, the wax crystals will grow rapidly, forming a planar crystalline First, these crystals interconnected, as well as a three-dimensional network structure, in which the oil, the oil loses its fluidity and showed coagulation status. Usually n-alkanes in diesel content of about 15% to 30%, when diesel fuel is cooled, as long as there is about 2% of n-alkanes precipitation, coagulation can make diesel fuel, diesel fuel at a certain temperature, depending on the amount of wax precipitation The type of diesel oil production, processing and blending scheme distillation range of diesel oil fractions and the blending ratio. Fill a square refinery filling program, filling preparation: As the winter of the product viscosity, pasty, it must prepare a special filling equipment and processes. Equipment required to prepare: 10-20 cubic tank a steam room heated by a heating (6-10 barrel can be heated to a Shanghai depressant, can be omitted if a special conservatory), a metering pump Taiwan (selected according to the dosage range). Prepare the process: low pressure steam heating process (through to the bottom of the heating room, blowing up), wind stirring process (instrument air to the tank through the lower pour point depressants, diagonal distribution, automatic cyclone), dosing Process (dosing point should be selected after the entrance outside the transmission pump diesel hydrogenation, the oil is appropriate at 40-60 ℃).
