In a continuous process for separating crude oil into two distinct fractions of high definition, crude oil is continuously introduced into a flow path having a portion relatively narrow in cross-section. Heat is supplied to the crude oil along the narrow cross-section portion of the flow path to volatilize one crude oil fraction thereby producing a mixture of a volatilized fraction and a residual liquid fraction. The rate at which the crude oil is introduced into the flow path, the narrow cross-section of the portion of the flow path and the heat supplied effect a high rate of volatilization, a high velocity of the mixture through the narrow cross-section portion of the flow path, and intimate contact between liquid and vapor fractions. After the residual liquid fraction and volatilized fraction mixture is discharged from the flow path, the volatilized fraction is allowed to separate rapidly and become isolated from the residual liquid fraction. |
