4.1. With 100,000 BPD of the following crude (API = 36), estimate the
products of the atmospheric distillation column. If the atmospheric
residue of the crude is taken at 650+ F. It enters in a vacuum distilla-
tion tower to give three products: light vacuum gas oil (650-850 °F),
heavy vacuum gas oil (850-1050 °F) and vacuum residue (1050+ °F).
Calculate the mass flow rate of these products. Then calculate the
sulphur content (lb/hr) for each product.
