Then, oil vapor in the column......... This oil refining process is called.. B as a result, hydrocarbons, in the molecules of which.......... the number of carbon atoms, rise in the column, and hydrocarbons, in the molecules of which......... the number of carbon atoms, are collected in the lower part of the column, since their boiling point.... Oil 35-180°C 200-350°C Vapor Oven >> 400°C

Answer 1

1) First oil is preheated in the oven. Then oil vapor in the column is flashed. This oil refining process is called distillation. As a result of which hydrocarbons, in the molecules of which less number of carbon atom(naptha,gases), rise in the column, and the hydrocarbon with more number of carbon atom(diesel,heavy oil) are collected in the lower part of the column, since their boiling point is more.
