Atmospheric and vacuum distillation process of crude oil can be intensified by adding the activators into the crude oil because the activators can adjust the petroleum dispersion system into the active state under which the light components in the crude oil can transform easily into gas phase from liquid one when the petroleum liquid is boiling. Therefore, this technology can not only increase the yield of light distillates but also improve their quantities in the crude oil distillation, which is very important to develop the new oil refining technology and resolve the contradiction of supplying and demand in the fuel market. In this paper, some advances in theory and practice in intensifying atmospheric and vacuum distillation process of the crude oil are briefly reviewed. At the same time, the paper both reveals many pivotal problems on the intensifying distillation process and predicts its trend in the future.
