Question
Chapter 2, Problem 2.51P
Interpretation Introduction
(a)
Interpretation:
The data should be plotted on logarithmic axes.
Concept introduction:
Assume x and y are two variables where y varies according to x.
The following (x,y) data are recorded,
| x | 0.5 | 1.4 | 84 |
| y | 2.2 | 4.3 | 6.15 |
So, we can draw a graph in logarithmic axes by taking x variable as the horizontal axis and y variable as the vertical axis.
Interpretation Introduction

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.
