Additives are frequently used to lower the pour point, ensuring functionality in cold environments. These chemical additives interfere with the formation of wax crystals, preventing them from aligning and growing large enough to impede flow.
How Additives Affect Viscosity and the Freezing Point of Oil
Additives and Cold Weather Solutions To combat the natural gelling of hydrocarbons, the industry utilizes pour point depressants. This process is what typically leads to the thickening or solidification we associate with oil freezing, even if the material is technically still in a semi-liquid state.
The pour point is the lowest temperature at which oil will still flow and be pumpable. Distinguishing Between Flow and Freeze Engineers and technicians often refer to the "pour point" rather than the freezing point.
How Additives Affect Viscosity and the Freezing Point of Oil
Pour point is usually a few degrees higher than the temperature at which the oil begins to solidify. This necessitates the use of heated storage tanks or insulation to maintain operational temperatures above the critical threshold.
