H.W 5.3:
120000 Lb/hr of 34 API crude oil at 650 F is fed to an atmospheric distillation unit. Steam at a
rate of 600 lb/hr and 850 F is used. The fraction obtained were 34000 lb/hr gasoline (MW=110,
1=120) at 310 F; 12000 lb/hr kerosene (MW=185, 2=108) at 420
F; 30000 lb/hr gas oil
(MW=270, A=95) at 510 F.
The residue is withdrawn at 510 F. Assume C = 0.7, C
