METHOD FOR PREPARATION OF PARAFFIN-RESIN-ASPHALTENE OIL FOR TRANSPORTATION AND PROCESSING Russian patent published in 1997 - IPC

Abstract RU 2084615 C1

FIELD: oil processing industry. SUBSTANCE: according to method, introduced into oil is high-molecular paraffin at temperature which is above paraffin melting temperature up to creating of saturated solution. Paraffin-resin-asphaltene conglomerate is introduced by cooling of solution down to temperature of saturation oil with paraffin. Cycles of extracting paraffin-resin-asphaltene conglomerate is repeated up to obtaining required degree of clearing and after that, resin- -asphaltene concentrate is separated from paraffin. EFFECT: high efficiency. 1 dwg , 1 tbl
