1. Introduction Technologically, a mini-refinery is a low-tonnage unit (with a capacity of up to 1 million tons/year) EDP-AVD (Electric Desalting Plant¡ªAtmospheric-Vacuum Distillation) [ 1 ], whose product streams are low-quality petroleum products: straight-run gasoline (naphtha) and diesel (gas oil) fractions, as well as fuel oil.
Which industrial technologies are used for vegetable oils’ refining?
The present review aimed at comparing the two main industrial technologies used for vegetable oils¡¯ refining, namely, chemical refining and physical refining. Chemical refining removes free fatty acids by soda neutralization.
What is alkaline refining?
This alkaline refining process is applicable for majority of the crude oils, including oils with low quality, except for castor oil (Zeldenrust 2020 ).
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:
