Pour point is the temperature at which a petroleum product changes from liquid to solid under test conditions. Lowering the pour point of petroleum products can improve their low-temperature fluidity and pumpability. It is generally believed that the change in pour point can be used as one of the low-temperature flow performance indicators of oil products. The purpose of pour point mainly includes the following aspects:
Determining the low-temperature fluidity of viscous or crystallized oil products: Pour point is one of the important indicators of the flow performance of petroleum products at low temperatures, and can reflect the fluidity and pumpability of oil products under low-temperature conditions. In cold seasons or regions, the low-temperature fluidity of petroleum products is particularly important, so measuring its pour point can help evaluate its performance in low-temperature environments.
Determine the use scope of oil products: Different types of petroleum products have different pour points. For example, oils with lower pour points are suitable for lubrication, cooling, etc., while oils with higher pour points are suitable for sealing, insulation, etc. Therefore, measuring the pour point of petroleum products can help determine their scope of use and applicable fields.
Evaluate the quality and stability of oil products: The quality and stability of petroleum products are also related to their pour point. Generally speaking, oil with a lower pour point has better quality and higher stability; while oil with a higher pour point may have impurities, moisture and other unstable factors. Therefore, determining the pour point of a petroleum product can help assess its quality and stability.
Guidance on production, storage and use: For units that produce, store and use petroleum products, it is very important to understand the pour point of petroleum products. During the production process, the pour point can be reduced by controlling the raw materials and production process; during the storage process, it is necessary to pay attention to conditions such as temperature and pressure to avoid solidification; during use, appropriate lubrication, sealing, cooling and other oils can be selected based on the pour point.
In short, pour point is one of the important indicators of petroleum products. It can reflect its low-temperature fluidity and usage range, help evaluate the quality and stability of oil products, and guide production, storage and use.
Pour point is a property of petroleum products, especially lubricants, and refers to the lowest temperature at which the oil will flow. Pour point indicates a product’s ability to flow and lubricate under low temperature conditions. This is an important characteristic to consider, especially for applications where the lubricant is used in cold climates or exposed to low temperatures. The lower the pour point, the better the low-temperature performance and fluidity of the lubricating oil.
