METHOD OF PRIMARY DISTILLATION OF HYDROCARBON RAW MATERIAL (GAS CONDENSATE AND OIL) Russian patent published in 2002 - IPC

FIELD: technological systems of module-type low-tonnage plants for development of small gas condensate and oil fields for local service pertaining to motor, boiler and furnace fuels. SUBSTANCE: preheated raw material is fed to separator-flash box at simultaneous delivery of non- condensed hydrocarbons ejected by flow of raw material fed to separator- flash box. Liquid separated in separator and additionally preheated vapor phase are directed in counter flow to absorption evaporation phase separator whose vapor phase is condensed and discharged to gasoline fraction product reservoir. One part of non-condensed hydrocarbons is discharged in form of fuel gas and remaining part is ejected by raw material flow into first-stage separator. Liquid phase (residue) thus obtained is directed from first evaporation stage to second evaporation stage. Mazut is introduced as liquid phase in form of residue. EFFECT: enhanced efficiency of procedure; facilitated procedure of distillation at minimum amount of equipment; enhanced operational safety; enhanced accuracy of separation; increased yield of white distillates. 1 dwg
