As a result, the diameter of the oil particles become large and separation efficiency improves.

The primary degree of this deterioration is the formation of hydroperoxides which attach  themselves to the carbon atom adjacent to the double bond.

It is virtually impossible in that case to determine the value of the reaction constant k because a plot of logarithm of acidity against time leads to curves having their concavity towards the t axis. The apparent rate of the reaction decreases very quickly as the reaction proceeds. Furthermore, aberrant results are recorded frequently owing to the very small amounts of moisture to be determined

Other criteria make it possible to assess the quality of crude palm oil.

A nozzle is fitted at the end of each of the branches. A constant volume of water is (5.4 t hr^-1) discharged through the nozzles. The level of the interface is not set by gravity discs but by two inverted centrifugal pumps (fixed rotor and rotating liquid). One of these pumps supplies enough water to ensure full discharge of liquid through the nozzles dash – the diameter of which could vary from (2 to 2.3 mm).

The complete refining of oil consists of the following operations: • separation of solid impurities that is impurities not soluble in oil, • separation of free water, • partial separation of dissolved moisture that is dehydration or drying, • de-gumming, • separation of free fatty acids or neutralization,  • separation, reduction or destruction of pigments, that is bleaching, and • separation, reduction of destruction of volatile compounds affecting odour or taste that is deodorization.
