Arefinery has just purchased a new crude with the following properties a. gravity: 21.5°api b. sulfur =2.7 wt. % c. tan = 1.3 mg koh/g d. salt content: 30 ptb (lb nacl/1000 bbl) e. for this crude answer the following: 1. what is the mass of 1 bbl of the crude oil ii. if all the sulfur in the oil were to be converted to elemental sulfur and recovered how much sulfur would be produced from 10,000 bbl of crude (report results in short tons per day)? lii. if 2 moles of h2 is needed to remove each mole of scontained in the crude, how many scf of h2/bbl of crude is required to remove the s? note: scf = std cu ft at 60 f) if the average mol wt of acids in the crude oil is 250 lb/1b-mole, what is the weight % of acids in the crude? if each mole of acid in the crude oil consumes 3 moles of h2, how many scfd (std cu ft/d) of h2 would by consumed by the acids in 10,000 bpd of the crude? vi. how many ppmw of chlorides does the crude oil contain? vii. if 20% of the chlorides hydrolyze to form hcl, how many pounds of hcl are generated by 1000 bbl of the crude? ni 2. what is the api gravity of water? what is the mass of 1 bbl of water at 60 °f?
