Petroleum is an important fossil energy, and petroleum products can be obtained through petroleum refining. Petroleum refining refers to the separation of various oils in petroleum to obtain various important petroleum products, such as gasoline and diesel. And petroleum distillation is one of the most important refining technology.

petroleum distillation is a process of separation using the different boiling points of various oils in petroleum. Specifically, the oil will produce a variety of oil boiling after heating, different oil boiling at different temperatures, oil distillation can use this feature to separate a variety of oils. The changes involved in the process of

petroleum distillation mainly include the following aspects:

1. Volatile separation: When petroleum distillation, due to the different boiling points of various oils in petroleum, in the process of heating, the low boiling point oil in petroleum will gradually evaporate.

2. Distillation separation: various oils in petroleum are separated in the process of evaporation. As the temperature increases, the various oils in the oil will gradually separate and collect at different temperatures.

3. sublimation separation: high boiling point oil in the oil distillation process can not be completely separated, then they need to be separated by heating sublimation, to achieve the final separation effect.

Through petroleum distillation technology, the oil that can be separated can not only be used to produce petroleum products, but also as petrochemical raw materials. At the same time, for the petroleum industry, petroleum distillation is also an energy-saving and environmentally friendly technology. Because in the process of petroleum distillation, the consumption of fossil energy is greatly reduced.

summary:

petroleum distillation is an indispensable technology for refining petroleum, and the changes behind it are also worthy of our understanding and exploration. Through petroleum distillation, we can not only obtain various petroleum products and petrochemical raw materials, but also reduce the consumption of fossil energy and achieve more energy-saving and environmentally friendly production. In the future, with the continuous upgrading and improvement of technology, petroleum distillation technology will also continue to develop, providing better technical support for petroleum refining.
