High temperature simulated distillation (ex. ASTM D7169, IP 545, EN 15199-2,-3) does not provide a complete and accurate boiling point distribution. That’s because the ‘front end’ boiling point distribution is distorted by the quenching effect of the carbon disulfide solvent (CS2) which co-elutes with the light components in crude oil.
Users of SimDis® Expert can easily overcome this problem by using our free ‘Merge Expert software which ‘merges’ DHA data with simulated distillation boiling point data. The result is a crude oil distillation curve that’s much more indicative of the true boiling point (TBP).
