Two-stage layout of VHC unit
with compression of cracking gases up to the pressure in fuel header of the plant and removal of acid components

1 - vacuum creating device
2,6 - separators
3,7 - heat exchangers
4 - pump for motive fluid (diesel fraction, gas oil)
5 jet device of compressor
8 - pump for motive fluid (sorbent of acidic gaseous admixtures)

I - gas-vapor mixture from distillation column
II gases to additional compression and treatment from acid components
III gas into fuel system
IV outlet of excess motive fluid
V feed of regenerated sorbent
VI discharge of sorbent to regeneration
VII fresh motive fluid makeup line

In this layout, the hydrocarbon motive fluid (diesel fraction or gas oil) is used in the first stage of compression and the sorbent of acidic gases (e.g., monoethanolamine solution) acts as motive fluid in the second stage, which allows to remove hydrogen sulphide from decomposition gases simultaneously with their compression.
