FIELD: oil and gas industry.
SUBSTANCE: invention refers to the method for removal of impurities from raw liquid, mainly hydrocarbons. The method includes the following stages carried out in the same vessel: contacting of raw liquid passing through the vessel with copper-based material in order to remove oxygen from raw liquid. Then raw liquid passing through the vessel contacts with several absorbents in order to remove one or more substances from it - water, carbon dioxide or acid-containing hydrocarbons, at that the absorbents are different at least at two stages. In this connection copper-based materials and several absorbents are placed in a single dense layer containing more than one layer for material treatment in the same vessel. The invention is also related to the system of impurities removal and regeneration method for the system of impurities removal.
EFFECT: use of this invention allows treatment of raw liquid in the same vessel at ambient temperature by materials used for treatment and regenerated thereafter in the same conditions.
