METHOD OF ASSESSMENT OF DISPERSING AND SOLUBILISING PROPERTIES OF FUELS AND OILS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01N33/22 G01N33/26 

FIELD: test equipment.

SUBSTANCE: group of inventions relates to test of fuels and oils and can be used for assessment of their operational properties. The method of assessment of dispersing and solubilising properties of fuels and oils includes test of the sample of the studied material at optimum temperature in the closed circulating system at which the circulating estimated oil or fuel is contacted with surface of the dissolved control substance which is prepared by its gradual heating up to the temperature 360°C with the subsequent holding within 4 hours, this substance is dissolved while it is contacted with the flow of circulating oil or fuel, periodically the parameters of its dissolution are recorded depending on temperature of circulating oils or fuels, as well as intensity of their circulation, size of surface of contact of tested substance with the flow of circulating oils or fuels, time of contact of the circulating oil or fuel with the surface of tested substance, while the dispersing and solubilising properties of oil or fuel are estimated by the rate of dissolution of tested substance which is estimated by decrease of weight of tested substance during its contacting with the flow of oil or fuel and by the content of tested substance comprised by the circulating flow of oil or fuel. Besides, the device for implementation of the above method is presented.

EFFECT: improvement of assessment reliability is achieved.
