1. Using one of the crude oils in Appendix C, make TBP and gravity midpercent curves. From these curves and the crude oil fraction specifications in Table 4.1 or Table 4.2, make a complete material balance around an atmospheric crude still. Assume a 100,000 BPCD crude oil feed rate to the atmospheric crude still. Make the balances to the nearest pound. 1. Using one of the crude oils in Appendix C, make TBP and gravity midpercent curves.
