Question: 1. Develop a TBP and gravity midpercent curve for one of the crude oils given in Appendix C. 2. Using the TBP and gravity

1. Develop a TBP and gravity midpercent curve for one of the crude oils given in Appendix C. 2. Using the TBP and gravity curves from problem 1, calculate the Watson characterization factors for the fractions having mean average boiling points of 550F (288C) and 750F (399C). Is it probable this crude oil will produce satisfactory quality asphalt? CRUDE PETROLEUM ANALYSIS Bureau of Mines Bartlesville.. Sample 55151...
