Hello

 

Has some of You ever come across how to convert distillation data ASTM d6352 to ASTM d7169 ?

 

Is it even possible ? Are there some algorithms ?

I tried to use HYSYS and Aspen Plus, but they have no such option in them. Also google can´t find any information .

 

I will be very grateful for any help .

 

 

Thanks in advance

Both of these distillation curves are generated via chromatography.  Elution times in the chomatograph are correlated to molecular weight which is then converted to boiling point.  If the lab is aware of the type of crude oil (PNA analysis) they should adjust the mole weights to account for the difference between paraffins and aromatics.  In this case, both D6352 and D7169 should be very close to TBP data.  At temperatures above 550°C the details don't matter much as this is a non-volatile range anyway.

 

I would consider D6352 and D7169 to be equivalent unless I had performed both tests on the SAME oil and showed a significant difference - at which point I would be asking the lab for detailed on EXACTLY how they are doing the test.
