Light sweet crudes generally perform better in low temperatures compared to heavy sour crudes. These tests involve cooling the sample in a controlled environment and observing its behavior at specific temperature intervals.
How Wax Crystals Cause Filter Clogging in Cold Temperatures
Pour point is usually a few degrees higher than the temperature at which the oil begins to solidify. While water freezes at a predictable 0 degrees Celsius, the behavior of oil is far more complex due to its chemical composition.
The pour point is the lowest temperature at which oil will still flow and be pumpable. When temperatures drop, these paraffin molecules begin to bond together, forming a crystalline structure.
How Wax Crystals Form and Cause Filter Clogging
Industry Standards and Measurement Standardized testing methods exist to determine the cold flow properties of oil. Additives are frequently used to lower the pour point, ensuring functionality in cold environments.
