METHOD OF GAS CONDENSATE AND LIGHT OIL SEPARATION AND PLANT TO THIS END Russian patent published in 2013 - IPC B01D3/14 C10G7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to processing of gas condensate and light oil. Proposed method comprises preheating of initial stock, stripping of light naphtha at first rectifier, feeding of bottom residue into second rectifier to strip heavy naphtha, kerosene and diesel fractions therein to obtain fuel oil as residue. Initial stock after preheating is subjected to single partial evaporation to direct obtained gas into first rectifier rectifying section and obtained fluid into first rectifier feed zone. Proposed plant comprises heated initial stock feed line, first rectifier with its top connected via first heat exchanger with light naphtha discharge line and bottom connected firs first heater with second rectifier, its top being connected with heavy naphtha discharge line, rectifying section has two outlets connected with appropriate evaporation columns to produce kerosene and diesel fuel. Its bottom is connected with fuel oil discharge line. It comprises evaporator of gasoline pre-separation with its top connected with first rectifier rectifying section and bottom connected with first rectifier feed zone.

EFFECT: lower load at first rectifier in vapor phase.
