Problem: A petroleum cut has the following ASTM D$86$ distillation data

$\backslash$table$[[$V$\%$ distilled,T$0,$T$10,$T$30,$T$50,$T$70,$T$90,$T$95],[$ASTM D$86C,36\mathrm{.}5,54,77,101\mathrm{.}5,131,171,186\mathrm{.}5]]$

a$.$ Convert ASTM to TBP using API method.

b$.$ Find the slope of EFV and $T_{50\%}$ if $T_{100\%}$ is $850F.$

c$.$ Estimate the MeABP.

d$.$ Find UOP characterization factor if the API of this fraction is $62.$

Problem: for the below TBP data, answer the following:

a$.$ From the crude distillation data, plot TBP and gravity$-$ mid$-$percent curves.

b$.$ Select TBP cut$-$points of products to be used in internal combustion engines.

c$.$ From TBP and gravity curves, determine percentages and gravities of fractions.
