FAQ
Q: What is the cloud and pour point test?
A: The Cloud Point is the lowest temperature at which a liquid sample becomes cloudy due to the formation of hydrocarbon crystals as the components start to precipitate during cooling. On the other hand, the Pour Point is the lowest temperature at which a liquid can still flow without external assistance, such as stirring, indicating its ability to remain mobile under cold conditions.
Q: What is the test method for the pour point?
A: The Pour Point test follows ASTM D97, where the sample is cooled in a bath to form paraffin wax crystals. At 9°C above the expected pour point and every 3°C thereafter, the jar is tilted to check for surface movement, determining the lowest temperature at which the liquid remains flowable.
Q: What are the factors affecting the cloud point and pour point?
A: The cloud point and pour point of petroleum products are influenced by factors such as additives and contamination. Pour point depressants can lower the pour point by preventing wax crystal formation, while contaminants like dirt or water can raise the pour point, affecting the product’s flow.
