Crude oil is fractioned by two separating columns. The incoming crude oil is composed of, in weight fractions, 0.0100 gas, 0.260 gasoline, 0.100 kerosene, 0.130 diesel, 0.130 heating oil, 0.120 lubricating oil, and the rest solids. The crude oil is fed into the first column at m₁ = 1.170 x 10³ kg/h, producing a stream of gas, a 5:1 gasoline to kerosene stream, a stream containing kerosene and diesel, and a m5 = 6.40 x 10² 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 m₁ = 194 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, 0.0100 gas,
0.260 gasoline, 0.100 kerosene, 0.130 diesel, 0.130 heating oil, 0.120 lubricating oil, and the rest solids. The crude oil is fed
into the first column at m₁ = 1.170 x 103 kg/h, producing a stream of gas, a 5:1 gasoline to kerosene stream, a stream
containing kerosene and diesel, and a m5 = 6.40 x 10² 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 = 194 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.
