WebThe method which was developed by Riazi and Daubert and published in the 1987 API Technical Data Book is used to convert each D2887 temperature to a D86 temperature: where: a, b,c = constants for each standard volume percent and D2887 and D86 are Deg R. Reference: Riazi M.R. and Daubert, T.E., Oil and Gas Journal, August 25, 1986, pp 50-57.

But, as per method, GC is typically operated within range of 360-390 C. So, is it possible to vaporize HCGO (370-530 C) sample (0.5-1 micro liter) at this operating temperature and hence, evaluate the TBP profile of HCGO? how many axles does an 18 wheeler have

WebThe boiling range for crude oil may exceed 1000 °F. The ASTM D86 and D1160 standards describe a simple distillation method for measuring the boiling point distribution of crude oil and petroleum products. Using ASTM, D86 boiling points are measured at 10, 30, 50, 70, and 90 vol% distilled. The points are also frequently reported at 0%, 5%, and ...
