What are the common experiences used in oil blending? Such as the blended flash point, freezing point, cold filter point, etc

As the title suggests: What are some common empirical rules for flash point, freezing point, cold filter point, corrosion, etc.? If the flash point requirement for diesel is above 55 degrees Celsius, and there are 100 tons of oil with a flash point of 50°C that do not meet this standard, how many tons of oil with a flash point of 60°C are needed to be mixed in order to ensure that the overall flash point meets the required standard? 700 tons? What are the experiences regarding freezing point, cold filtration point, dry point, corrosion, and so on? ? ?
There is no dry point or corrosion, but there are cold filter point, freezing point, and flash point
For cold filter point, freezing point, and flash point, what are the methods used for adjustment?
What are the common practices used in oil blending? Parameters such as the blended flash point, freezing point, and cold filter plugging point are taken into consideration during oil blending. Oil blending involves testing the properties of various petroleum fractions; based on characteristics like density, cetane number, octane number, boiling point, viscosity, and impurity content, the fractions are blended in accordance with national standards in order to achieve **standard fuel quality at the lowest possible cost. In addition to petroleum fractions, the blending of Zhongtong Environmental Protection fuels also includes chemical additives (mainly liquid fuels) as well as various types of used oil (used engine oil, tire oil, plastic-derived oil, etc.). Blending is carried out either in accordance with national standards or alternative standards, enabling these fuels to meet the requirements of imported vehicles, domestic vehicles, high-speed engines, low-speed engines, etc., and they also fall within the category of thermal energy fuels.
The oil flash point is required to be above 55 degrees Celsius; there are 100 tons of oil that do not meet this standard, with a flash point of 50 degrees Celsius
There is no dry point or corrosion, but there are cold filter point, freezing point, and flash point
The oil flash point requirement is above 55 degrees Celsius
Is there anything more about diesel? There are empirical formulas available for determining the condensation point and lightning, and it would be best to have actual experimental data for comparison in order to derive one’s own empirical formula
The flash point cannot be increased through blending.
It’s relatively simple to adjust this; I’ll share my simple opinions in the hope they will be helpful to you. First of all, the flash point depends on the content of light components in the oil – more light components result in a lower flash point, while fewer lead to a higher one. I’m not familiar with the specific formulas used for this calculation. When two oils with different flash points are blended together, the flash point tends to increase slightly. It’s sufficient to create a small sample and measure its flash point. The freezing point and pour point depend on the content of paraffin; generally, the paraffin content in O# oil is higher than that in -10# oil, and when these two are blended, the resulting oil has a freezing point of -5#. It’s also possible to use 200# oil, aviation fuel, and antifreeze agents for blending. As for the dry point, it’s important to keep the distillation range of the oil from being too wide. For copper sheet corrosion resistance, hydrogenated oils usually have a rating of 1A
