COMPARISON OF METHODS FOR MEASURING PARAFFIN CONCENTRATION IN CRUDE ON THE EXAMPLE OF CRUDE <VITYAZ>
It is shown that the measurement of the concentration of wax (paraffin) in the crude «Vityaz» methods SMS 1769/88, GOST 11851-85 and gas chromatography (GC) produce similar data. The concentration of wax in the crude «Vityaz» ranges from 0.9 to 1.2% (by weight) depending on the method used. Using GC it was found that n-alkanes from C20 to C60 are present in the wax isolated from crude «Vit- yaz» by GOST 11851-85 method.
