Layout of the two-stage VHC unit
with hydrocarbon motive liquid

1,2 vacuum creating devices
3,4 - separators
5 heat exchanger
6 pump for motive liquid (diesel fraction, gas oil)

I gas-vapor mixture from distillation column
II cracking gases for combustion
III, IV motive liquid excess withdrawal line
V fresh motive liquid makeup line

Compression of the gas-vapor mixture is performed in two stages due to energy of hydrocarbon motive liquid. In comparison with layout of one-stage vacuum hydrocirculating unit, this reduces energy consumption of the motive liquid pump.
