Crude oil is fractioned by two separating columns. The incoming crude oil is composed of the following weight fractions: 0.0200 gas, 0.260 gasoline, 0.100 kerosene, 0.120 diesel, 0.130 heating oil, 0.110 lubricating oil, and the rest solids. The crude oil is fed into the first column at 1.180 × 103 kg/hr producing a stream of gas, a 5:1 gasoline to kerosene stream, a stream containing kerosene and diesel, and 685 kg/hr 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. If you want to produce 222 kg/hr 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.
