Why do mini-refineries use a vacuum unit for oil refining?
Such schemes of oil refining at mini-refineries are related to the fact that for road works, which are characterized by seasonality, bitumen is needed; it is more expedient to obtain and process bitumen on site than transport it from large refineries. Consequently, the vacuum units of such refineries will be operated in different operating modes:
What are Akfen mini refineries?
Akfen Mini-Refineries are skid mounted, modular crude oil distillation units (CDU) which process from 22.000 Liter of crude oil per Day and are capable of producing a variety of finished products including naphtha (straight run gasoline), kerosene, arctic and summer diesel and fuel oil. A reformer may be added for producing high-octane gasoline.
What is vacuum distillation?
Vacuum distillation is acommon method to separate mixture components under reduced pressure. Vacuum distillation is mostly utilized to allow lower boiling point compounds to separate from higher boiling point compounds in the mixture introduced in a vacuum tower.
What is the difference between mini-refineries in Russia and large-scale production?
The key difference between the vacuum units of mini-refineries in Russia from large-scale production is that the main product obtained is road bitumen and tar, and not vacuum distillates.
