Efficient diesel cold flow improvers (PPD)

I. Overview: efficient diesel cold flow improver is my company and research institutes jointly developed a new type of cold flow improvers, pour point depressants it is different from the ordinary, not only has the function of reducing diesel pour point, and can effectively change diesel low temperature precipitated crystalline size and shape of the wax, the wax can not condense crystallization becomes smaller. Therefore, to reduce diesel cold filter plugging point is very valid. The product is prepared from a compound having a specific chemical structure and molecular weight of from. XLW-1805 effect in a leading position, its pour bigger than 25 ℃, reduce the cold filter plugging point about 10 ℃. Suitable for straight run diesel, hydrotreated diesel fuel, diesel oil and blending thermal cracking diesel, oil refining companies can also use it to improve the low temperature fluidity of the heavy components, increase the proportion of blending components for enterprises to increase efficiency. Second, the nature: Item (unit) Index Test Method Appearance White or light yellow liquid Density (20 ℃, g / cm3) 0.85 ~ 0.95 GB / T1884-92 kinematic viscosity (40 ℃, m㎡ / s) 50 ~ 100 GB / T265-88 Third, use: 1, in addition to its own nature, pour the effect is also closely related to the oil composition and distillate range and blending methods. Therefore, to be tested before use to determine the amount and preparation programs should try to maintain a stable oil properties. 2. Add the General ton diesel add 0.3 ~ 1.0Kg. 3, first with a low pour point diesel will are diluted 10 times, and then mixed with diesel oil, mixed with a static mixer or pumped circulation to achieve mixing (mixing time is generally 4 hours). 4, add this agent requires blending in diesel fuel pour point temperature is higher than the above 10 ℃, if the preparation of additives for diesel heated to about 40 ℃, the better. 5, the winter if there modifiers solidification phenomena, can be heated to melt before use. Fourth, packaging and storage: 1, with costumes 200L galvanized barrels, net weight 180 ± 0.5 kg. 2, this product is flammable and should be stored in a cool, ventilated, avoid direct sunlight, away from fire and heat. 3, the product moisture would affect the results, so this product in storage, is strictly prohibited contact with water use.
