【Basic Knowledge Activity】Professional “Basic Knowledge” in the petrochemical industry: What is the cold filter point of petroleum products?

The cold filter point is the highest temperature at which, under the testing conditions specified in SH/T 0248, the flow rate of the test sample through the filter is less than 20 mL per minute. Since the determination conditions for the cold filter point are similar to the operating conditions, it can be used to roughly determine the lowest temperature at which diesel can be used. The level of the cold filter point is related to the low-temperature viscosity and wax content of diesel. High viscosity at low temperatures or an excessive amount of wax crystals can both raise the cold filter plugging point of diesel.

This initiative encourages various sections to organize, or individuals to create, posts on basic knowledge topics (the content can be gathered from the Internet or created originally; participation can take place through multiple themes, with no restrictions on the approach used – it could be an explanation of a noun or an introduction to a series of principles). What are some suggestions and methods for getting in touch with cleaners? The regular administrator will reward the content that performs excellently. You will also be rewarded for regions where the activities are more intensive. (Regions should also carry out consolidation and optimization based on the amount of such content available in their area.) ———————————————— The second phase of the event runs from February 20, 2016, to the end of June 2016; at least 50 award vouchers are available for you to claim (mugs, power banks, USB drives, and other prizes or event benefits).

The freezing point refers to the highest temperature at which, under specified test conditions, the surface of the cooled oil sample stops moving, and it is expressed in °C. Freezing point and cold filter plugging point are important indicators for characterizing the low-temperature performance of diesel. The freezing point (SP) is the highest temperature at which diesel loses its fluidity in low-temperature conditions ； The Cold Filter Plugging Point (CFPP) indicates the highest temperature at which diesel can cause clogging of the filters in a diesel engine’s fuel supply system. For light diesel, the cold filter plugging point is a more important indicator than the freezing point in practical use. This is because the cold filter plugging point is directly related to the low-temperature performance of diesel, whereas the freezing point is mainly associated with the storage and transportation of diesel.
What is the cold filter point of oils? The cold filter point is an indicator that reflects the low-temperature operating performance of diesel.
The highest temperature at which the oil level of the cooled oil stops moving
The cold filter point is the highest temperature under the testing conditions specified in SH/T 0248, at which the flow rate of the oil sample through the filter is less than 20 mL per minute. Since the determination conditions for the cold filter point are similar to the operating conditions, it can be used to roughly determine the lowest temperature at which diesel can be used. The level of the cold filter point is related to the low-temperature viscosity and wax content of diesel. High viscosity at low temperatures or an excessive amount of wax crystals can both raise the cold filter plugging point of diesel.
The cold filter point refers to the highest temperature under specified conditions, when less than 20 ml of the test oil passes through the filter per minute.
The cold filter plugging point is the highest temperature at which diesel can cause clogging of the filters in a diesel engine’s fuel supply system.
The maximum temperature under specified conditions when the flow rate of the test fluid through the filter is less than 20 ml per minute
The cold filter point refers to the highest temperature under specified conditions, when less than 20 ml of the test oil passes through the filter per minute.
What is the cold filter point of petroleum products? Answer: The cold filter point is the highest temperature at which, under the testing conditions specified in SH/T 0248, the flow rate of the test sample through the filter is less than 20 mL per minute. Since the determination conditions for the cold filter point are similar to the operating conditions, it can be used to roughly determine the lowest temperature at which diesel can be used.

High viscosity at low temperatures or an excessive amount of wax crystals can both raise the cold filter plugging point of diesel.
The cold filter point refers to the highest temperature under specified conditions, when less than 20 ml of the oil sample passes through the filter per minute. (It is the lowest ambient temperature used for determining the flow point.)
