CONTINUOUS METHOD OF SEPARATION OF THE COLORED MASSES AND-OR THE ASPHALTENE IMPURITIES FROM THE HYDROCARBON MIXTURE Russian patent published in 2007 - IPC C10G31/11 

FIELD: petrochemical industry; other industries; methods of the continuous separation of the colored masses and-or the asphaltene impurities from the hydrocarbon mixture.

SUBSTANCE: the invention is pertaining to the continuous separation of the colored masses and-or the asphaltene impurities from the hydrocarbon mixture. The method is realized by gating of the part of such mixture through the diaphragm, on which they keep the differential pressure. As a result produce the hydrocarbon permeate with the reduced contents of the colored masses and-or the impurities. At that the differential pressure through the diaphragm during the separation process makes 5-60 bar, and reduction of the differential pressure through the diaphragm in the regular time intervals reduces its value up to 0-5 bar. The invention ensures the long-term operational cycle at the high average speed of the flow of the raw.

EFFECT: the invention ensures the long-term operational cycle at the high average speed of the flow of the raw.
