METHOD OF DEHYDRATING HEAVY PYROLYSIS TAR EMULSION Russian patent published in 2003 - IPC

Abstract RU 2201430 C1

FIELD: petroleum processing. SUBSTANCE: in a method wherein aqueous emulsion is dehydrated by mixing it with demulsifier and settling to form two-phase system, which is then separated into phases, after mixing of aqueous with emulsion demulsifier, aqueous solution of mineral salts is added having salt concentration corresponding to at least 50% saturation of aqueous solution, weight ratio of emulsion-demulsifier mixture to salt solution ranging from 1:0.5 to 1:10. EFFECT: increased dehydration degree to less than 1 wt % water. 1 tbl, 5 ex
