METHOD OF INRUSH OIL POLAR COMPOUNDS IN THE PROCESS OF ITS TRANSPORTATION BY MAIN OIL PIPELINE Russian patent published in 2018 - IPC C10G21/16 C10G21/28 C10G25/00 C10G29/22 B01D17/25 

FIELD: transportation and storage.

SUBSTANCE: invention relates transport and storage of oil, namely to the field of extraction of polar compounds of oil during its transportation by the main pipeline. Method of inrush oil polar compounds in process of its transportation by the main pipeline is characterized by the fact, that in the flow of oil flowing by the main pipeline, glycerin is introduced to absorb oil polar compounds, then flow of oil with glycerin is directed to a tank, defend to the formation of lower glycerol layer containing polar compounds of oil, which is then directed to an external adsorber, where selection of polar compounds of crude oil is carried out.

EFFECT: technical result is to reduce the loss of extractant, reducing volume of consumed extractant, improving quality of oil and improving its fractional composition due to the use of glycerin as an extractant, that does not mix with either aliphatic or aromatic compounds of oil.
