Explore the Cloud and Pour Point Apparatus, an essential tool for determining the lowest temperature usability of petroleum products. Discover its working principle, technical specifications, and unique features designed to provide accurate and reliable measurements for the oil industry.
Working Principle of the Cloud and Pour Point Apparatus
The Cloud and Pour Point Apparatus operates by progressively cooling a petroleum sample and observing its behavior at different temperatures. The process involves two key measurements:
- Cloud Point: This is the temperature at which a petroleum product first exhibits a cloudy appearance due to the formation of wax crystals. The sample is cooled in the apparatus, and light-pulsed emission with an I.R. spectrum and a coaxial fiber optic system is used to detect the initial haziness.
- Pour Point: This is the lowest temperature at which the petroleum product remains pourable. A PT100 probe, coupled with a mechanical arm, monitors the sample as it is cooled further. The temperature at which the sample stops flowing is recorded as the pour point.

Frequently Asked Questions (FAQ’s)
What instrument is used to measure cloud point?
Answer: The instrument used to measure the cloud point is called a Cloud and Pour Point Apparatus.
What is the cloud point and pour point determination?
Answer: Cloud point determination involves cooling a liquid and observing the temperature at which it first becomes cloudy due to the formation of wax crystals. Pour point determination involves further cooling to find the lowest temperature at which the liquid still flows.
What is cloud point and pour point in engineering chemistry?
Answer: In engineering chemistry, the cloud point is the temperature at which wax crystals first form in a liquid, making it appear cloudy. The pour point is the lowest temperature at which the liquid remains pourable or fluid.
What is the relationship between cloud point and pour point?
Answer: The cloud point is typically higher than the pour point. The cloud point indicates the onset of wax crystallization, while the pour point indicates the temperature at which the liquid stops flowing.
