Effect of hydrocarbon type in a ternary n-alkane mixture on heavy organics precipitation from crude oil at constant volume ratio and total volume

Abstract: Different hydrocarbon type mixtures at a fixed volume ratio and for any fixed total volume of the n-alkanes/g of oil were used to generate heavy organic solid precipitates from crude oil residue. The effect of n-alkane types in a precipitant mixture needed to be known. For 15mls/g oil, C5:C7:C8 gave the maximum precipitate value of 1.9% wt while C5:C6:C7 gave the least – 0.6% wt, for 30mls/g oil, C5:C6:C7 gave the maxima (2.4% wt) while C5:C6:C8 gave the minima (1.3% wt), for 45mls/g oil, C5:C6:C7 gave the maxima (1.7% wt) while C6:C7:C8 gave the minima (0.8% wt), for 60mls/g oil, C5:C6:C7 gave the maxima (1.2% wt) while C5:C6:C8 gave the minima (0.7% wt), for 75mls/g oil, C5:C6:C7 gave the maxima (1.2% wt) while C5:C6:C8 gave the minima (0.7% wt). Varying hydrocarbon type mixture at a fixed volume ratio and for any fixed total volume of the n-alkanes/g of oil affects precipitate yield differently. And it can be deduced here that susceptibility of oil to precipitation is a function of the n-alkane types present in the oil.
