The CRACKING of 1,2-dichloroethane takes place in a cracking furnace at approximately 480 °C. The heat value of the cracking gas is used for evaporating and superheating the EDC feed. The operating periods between two de-coking periods are very long (up to 2 years).

The advantages of the Vinnolit process can be summarized as follows:

· High reliability due to low coke formation
· High savings in primary and secondary energy, due to:
..- External EDC pre-evaporation using cracking gas heat
..- Utilisation of flue gas heat to preheat EDC, to preheat combustion air or to generate steam
· Low maintenance costs
· Proven materials and reliable equipment
