Licensor data for these conditions are:
Yield of reformate = 79.5 %LV
Reformate make = 6,851.5 BPCD
Hydrogen made = 5.13 MMscf/CD purity is 70 mol%
Then reformer gas is 5.13 Ä 0.7 = 7.33 MMscf/CD
Mol Wt of reformer gas is 12 as given by the licensor. Then MM lbs/CD of the
gas is 0.237.
C 5 = reformate = 6,851 BPCD and at an SG of 6.604 lbs/gal lbs/CD of
reformate = 1.9 MM lbs/CD.
Light ends leaving the reformer stripper will be in accordance with the following
balance:
lbs per CD of fresh feed = 2.276 MM lbs
lbs per CD of reformate = 1.900 MM lbs
lbs per CD of reformer gas = 0.237 MM lbs
By difference Lt ends = 0.152 MM lbs/CD routed to reformate stabilizer.
The reformer material balance is shown in Table 27.
