Crude oil is fractioned by two separating columns. The incoming crude oil is composed of, in weight fractions, 0.0500 gas, 0.240 gasoline, 0.100 kerosene, 0.120 diesel, 0.110 heating oil, 0.100 lubricating oil, and the rest solids. The crude oil is fed into the first column at m₁ = 1435 kg/h, producing a stream of gas, a 5:1 gasoline to kerosene stream, a stream containing kerosene and diesel, and a ms = 753 kg/h stream of the bottoms. The bottoms, containing diesel, lubricating oil, heating oil, and solids, is fed into a second distillation column that separates the components into three streams. The top stream contains diesel and heating oil. The middle stream contains heating oil and lubricating oil, and the bottom stream contains the solids. To produce my = 207 kg/h of the stream containing heating and lubricating oil, find 1. The flow rate, m3, of the gasoline and kerosene stream. 2. The composition of the heating oil and lubricating oil stream. 3. The composition of the diesel and heating oil stream.

Crude oil is fractioned by two separating columns. The incoming crude oil is composed of, in weight fractions, 0.0500 gas,
0.240 gasoline, 0.100 kerosene, 0.120 diesel, 0.110 heating oil, 0.100 lubricating oil, and the rest solids. The crude oil is fed
into the first column at m₁ = 1435 kg/h, producing a stream of gas, a 5:1 gasoline to kerosene stream, a stream containing
kerosene and diesel, and a m5 = 753 kg/h stream of the bottoms. The bottoms, containing diesel, lubricating oil, heating oil, and
solids, is fed into a second distillation column that separates the components into three streams. The top stream contains diesel
and heating oil. The middle stream contains heating oil and lubricating oil, and the bottom stream contains the solids. To
produce m7 = 207 kg/h of the stream containing heating and lubricating oil, find
1. The flow rate, m3, of the gasoline and kerosene stream.
2. The composition of the heating oil and lubricating oil stream.
3. The composition of the diesel and heating oil stream.
