FIELD: jet devices.
SUBSTANCE: the invention is dealt with the field of jet devices and may be used in petroleum and chemical industries. The method provides for feeding by a pump of a liquid medium into a liquid-gaseous jet device, pumping-out by the latter from a container being filled in with petroleum and-or from a container used for storage of petroleum of steam-gaseous medium and its compression in the liquid-gaseous jet device at the expense of energy of the liquid medium, feeding of the mixture of a steam-gaseous and a liquid mediums formed in the liquid-gaseous jet device into a separator, separation of the mixture for a gaseous phase and a liquid medium in the separator. At that the gaseous phase from the separator is fed into an absorption column, in which as an absorbent the hydrocarbonaceous liquid is fed. In the absorption column they conduct a process of absorption by a hydrocarbonaceous liquid of hydrocarbons from the gaseous phase. Then the gaseous phase purified from hydrocarbons and the hydrocarbonaceous liquid with dissolved in it hydrocarbons of the gaseous phase are separately removed from the absorption column. At that in the capacity of the petroleum product and the hydrocarbonaceous liquid the use gasoline or kerosene and before feeding them into the absorption column the gasoline or kerosene is cooled down the temperature located in the range from minus 10°С up to minus 50°С, and the mixture of steam-gaseous and liquid mediums formed in the liquid-gaseous jet device, that is to be fed into the separator, is compressed up to pressure from 0.20 MPa up to 1.50 MPa. The invention allows to reduce losses of petroleum products and to increase efficiency of purification of the steam-gaseous medium from hydrocarbons.
EFFECT: the invention allows to reduce losses of petroleum products and to increase efficiency of purification of the steam-gaseous medium from hydrocarbons.
