Process Description
VCM (vinyl chloride monomer) is produced by the gas phase pyrolysis of EDC (ethylene
dichloride), to yield equimolar amounts of VCM and HCl (hydrogen chloride) as the coproduct.
A balanced process utilizes HCl with oxygen and ethylene to produce more
intermediate EDC via oxychlorination route (fixed bed reactor).
Characteristics of the process:
- High selectivity of EDC to VCM and ethylene to EDC
- High VCM product purity (99,98 %)
- Energy efficiency:
Exotermic heat of oxychlorination process and heat recoverd from the high
temperature zone of the condensation train are used for process integration.
- Environmental friendly process:
- All liquid and gaseous wastes are completly incinerated where heat of
combustion is recovered by generating medium pressure steam.
- Any process water obtained undergoes treatment.
