EDC CRACKING Process
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 EDC cracking process can be summarized as follows:
The advantages of the Vinnolit EDC cracking process can be summarized as follows:
| · | high reliability |
| · | reliable equipment |
| · | proven materials |
| · | low coking rate |
| · | high cracking rate of up to 60 %, and hence lower energy cost and lower investment costs for the cracking furnace and the EDC and VCM distillation units |
| · | high savings in primary energy, due to |
 | - external EDC evaporation using the energy of the cracking gas |
| - energy recovery of flue- and cracking gases |
| - steam generation or EDC preheating situated on top of the quench column
