Pour point depressants improve the oil's ability to flow at lower temperatures.

Therefore as the ladle is rotated the actual pouring point has very little movement.

Therefore, the pour point may give a misleading view of the handling properties of the oil.

The lower pour point is measured by first pouring the sample into a stainless steel pressure vessel.

PPEs have the disadvantage of having somewhat high pour points.

The resulting fuel is superior for cold winters, due to its exceptionally low cloud and pour points.

The lowest temperature at which movement is detected on the sample surface is determined to be the pour point.

Two pour points can be derived which can give an approximate temperature window depending on its thermal history.

Tarakan oil field produced a light, sour crude oil with an unusually low pour point.

The D5949 test method determines the pour point in a shorter period of time than manual method D97.

Their specially designed properties allow a wider temperature range at higher and lower temperatures and often include a lower pour point.

Some technically important properties include: flash point, fire point, cloud point, and pour point.

Development of a series of pour point depressants for transportation of high waxy crude oils.

An approximate range of pour point can be observed from the specimen's upper and lower pour point.

This peculiarity happens because wax crystals form more readily when it has been heated within the past 24 hrs and contributes to the lower pour point.

The oil must kept warm (above its pour point) in the fuel oil storage tanks to prevent the oil from congealing and becoming unpumpable.

There are a number of commercially available additives that will significantly lower the pour point and cold filter plugging point of pure biodiesel.

The sample is then cooled and then inspected for pour point as per the usual pour point method.

Some background knowledge about pour point and different measuring methods (manufacturer of pour point tester)

They act to reduce the formation of wax crystals in the fuel, thereby lowering the pour point and the gel point of the fuel.

There are plans for the pipeline to process High Pour Point crude oil extracted at Barmer, Rajasthan in the near future.

At about 9 C above the expected pour point, and for every subsequent 3 C, the test jar is removed and tilted to check for surface movement.

Other products include colorimeters, centrifuges, oxidation stability units, automatic titration units, and cloud point and pour point testers.

For the fuel to become pumpable again, it needs to be brought above the gel point temperature to the Ungel point, which is typically near its pour point.

In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material.
