Abstract: Heavy organic precipitates were generated from crude oil residue using different volume ratios of ternary n-alkanes mixtures: C5:C6:C7, C5:C6:C8, C5:C7:C8 and C6:C7:C8. The ratios; 1:2:3, 1:3:2, 2:1:3, 2:3:1, 3:1:2 are 3:2:1 was considered. At a fixed total volume of 15mls/g oil, C5:C6:C7 had maximum HOS yield at 3:2:1 ratio, (5.7% wt), and minimum at 1:2:3 ratio (4.1% wt). C5:C6:C8 had maximum HOS yield at 2:3:1 ratio (4.9% wt) and minimum value is at the ratio 3:1:2 (2.9% wt). C5:C7:C8 had maximum HOS yield at 2:3:1 ratio (4.2% wt) and minimum value is at the ratio 1:2:3 (3.1% wt). C6:C7:C8 had maximum HOS yield at 2:3:1 ratio (3.4% wt) and minimum value is at the ratio 1:2:3 (2.5% wt). At 45mls/g, C5:C6:C7 had the highest HOS value at the ratio 3:2:1 (2.1%wt) and minimum at 2:1:3 (1.4% wt). C5:C6:C8 had the highest HOS value at the ratio 2:3:1 (1.2%wt) and minimum at 2:1:3 (0.8% wt). C5:C7:C8 had maximum HOS yield at 3:2:1 ratio (1.2% wt) and minimum value is at the ratio 1:2:3 (0.6% wt). C6:C7:C8 had maximum HOS yield at 3:1:2 ratio (1.1% wt) and minimum value is at the ratio 2:1:3 (0.8% wt). And at 75mls/g C5:C6:C7 had the maximum HOS yield at 3:2:1 (1.2% wt) and minimum at 2:1:3 (1.0% wt). C5:C6:C8 had the maximum HOS yield at 3:2:1 (1.3% wt) and minimum at 2:1:3 (0.6% wt). C5:C7:C8 had maximum HOS yield at 2:3:1 ratio (0.7% wt) and minimum value is at the ratio 1:2:3 (0.5% wt). C6:C7:C8 had maximum HOS yield at 2:3:1 ratio (0.7% wt) and minimum value is at the ratio 1:3:2 (0.6% wt). Analysis of variance shows that yields at varying volume ratios at different fixed total volume for same combination are significant since P-value here (0.0001) <5%. The results have shown that varying volume ratios affects HOS yield differently.
