Beschreibung
Zusammenfassung:	FIELD: petroleum processing. SUBSTANCE: petroleum is heated to be separated into residual fraction and vapor fraction and the latter is taken off, condensed, and collected. Fractionation is carried out by way of producing high-developed evaporation surface in vortex film evaporator in the form of thin twisted film of petroleum followed by intensive evaporation thereof upon additional steam-heating of evaporation surface. Vortical tube are provided with twisting device in the form of screw with double rectangular thread and conical narrowing of screw passage for feeding petroleum by two thin flows tangentially to inside surface of vortical tube. EFFECT: simplified process enabling its application directly under oil-field conditions. 2 dwg
