Problem with antifreeze addition

I want to know this too; it’s holding up. Looking forward to the master’s answer

As far as I know, there’s no way. The diesel grade is like a person’s name; it’s easy to change the name but difficult to change the surname

Reply to 3# mpcchuang: What does it mean? ? I’m a bit confused by what you’re saying. . . There are many different grades of diesel. . . .

I mean, an adult named Zhang San is 1.8 meters tall, while Li Si is 1.5 meters tall. Li Si cannot grow to be 1.8 meters tall. Similarly, adding a antifreeze agent to 0# diesel does not turn it into -30# diesel; it can only lower its viscosity a little bit

Reply to 5# mpcchuang: Our equipment, with the addition of antifreeze agents, can be used to produce -10# product. . . What device can produce lower-grade products?

This diesel antifreeze can rapidly lower the freezing point of diesel, effectively refine wax crystals, reduce the cold filter plugging point, and further improve the low-temperature flow properties of the oil; it is a next-generation high-tech product. d7 o( j" @3 f9 V% Q0 |. t 0 M& W!

Product performance: 3 E% {* A; Q, E$ f3 F It is mainly used as an additive for 0# -10#, -20#, and -35# diesel fuels, enabling the freezing point of these fuels to be reduced by 15—30 °C. The cold filter point is reduced by 4–12°C, achieving the goal of improving diesel flow at low temperatures. This allows the diesel fraction to become wider, increases the yield of diesel, and enhances the profitability of refineries.

Thickening agents only serve as an auxiliary measure; typical thickening agents can lower the cold filter point by 3-10 degrees, and they are not effective for all types of oils. In general, paraffin-based oils are more difficult to modify in terms of their cold filter point, while naphthenic-based oils are easier to adjust – in some cases, the cold filter point can be lowered by more than ten degrees. The recommended addition ratio is 600-1200 ppm

Atft units can produce diesel with a low freezing point, including military-grade diesel. Of course, this depends on the type of crude oil used. Advertisements for antifreeze agents are often exaggerated

A fuel additive with a low freezing point is added to the raw material in order to reduce the freezing point of diesel

The effectiveness of antifreeze agents depends not only on the properties of the agents themselves but also closely on the composition of the oil to which they are added. When a demulsifier is added to diesel with different compositions, the degree to which the cold filter point is reduced (i.e., the sensitivity) varies significantly; therefore, it is necessary first to select the most suitable demulsifier based on its sensitivity to that particular type of oil. Secondly, based on the composition and properties of the oil to be added, laboratory tests must be conducted to determine the optimal dosage.
