Crude Oil Centrifuge Machine, Low Speed 4000rpm

Why Test Water and Sediment in Crude Oil by Centrifuge?

• Check the water content of the oil well, approve the output, and take water plugging measures in time.
• Check the dehydration effect of crude oil at each oil gathering station in order to take further dehydration measures.
• Check whether the water content of the crude oil before processing and refining exceeds the process regulations.
• The need for custody transfer.

Working Principle of crude oil centrifuge

Put equal volumes of crude oil and water-saturated toluene solution into a conical centrifuge tube. After centrifugation, read the volume of water and sediment at the bottom of the tube.

NOTE: The measurement result is the total amount of water and sediment in the crude oil. In terms of water content alone, the measurement result is often lower than the actual water content, which can be considered as low precision. The advantages of this method are simple operation, fast speed, and relatively safe, and it is suitable for the determination of large quantities of crude oil with high water content.

Centrifuge Process of Oil Test

• Add the sample to the 50 mL mark of the two centrifuge tubes.
• Add 50 mL of toluene solution saturated with water in a constant temperature bath of 60℃±3℃ or 71℃3℃ to the upper meniscus into the two centrifuge tubes.
•  Add 0.2 mL of demulsification solution to each centrifuge tube.
• Close it tightly and invert it 10 times to ensure that the sample and the toluene solution are evenly mixed.
• Put the centrifuge tubes in the horizontal rotor of a heated thermal centrifuge machine, balanced the tubes, set the temperature at 60℃±3℃ ,15 min.
• Keep thermal centrifuge heated,centrifuge at 600 xg, 10 min.
