PPD diesel, also known as low-temperature fluidity improver diesel fuel, diesel fuel production is a common additive. PPD diesel refinery diesel yield, increase production flexibility and diesel, gasoline ratio, has a clear role in improving economic efficiency. For users of diesel for transportation and diesel PPD, due to the application of depressant, can significantly improve the low temperature performance. Chinese name diesel PPD nickname POUR improver additive category features improve productivity and diesel, gasoline ratio depressant to join, you can change the shape or size of the wax crystal wax crystal flexibility, but does not prevent the wax crystals precipitation and reduce the amount of wax precipitation. Therefore, the lowest wholesale diesel PPD, the role of direct supply depressant depressant diesel, diesel fuel when the temperature is lowered to close the cold filter plugging point, the diesel will appear in a large number of fine particles of wax crystals, so that the oil becomes cloudy appearance, but this does not affect diesel smoothly through the filter (or filters). According to the pour point of light diesel oil into different grades, each grade has a corresponding pour point and cold filter plugging point index. 0 refers to the grade of light diesel oil for diesel pour point depressant is not higher than 0 ℃ diesel manufacturers, the corresponding index for cold filter plugging point of no higher than + 4 ℃. So people often think, No. 0 diesel oil to show that it can be used normally at 0 ℃, which is actually a misunderstanding. Precisely, the pour point of No. 0 diesel 0 ℃ only in higher than the temperature of the cold filter plugging point + 4 ℃ in order to work properly, and in the cold filter plugging point and below the temperature of the diesel has been unable to pass filter net (or filters); when the temperature dropped to 0 ℃, the oil will lose mobility and showed coagulation status.
