Is the ethylene content high in coking dry gas?
Thread Content
The ethylene content in the dry gas from our plant’s coking process is around 7–8%. What are the potential hazards, and what causes this? How can the ethylene content be reduced? I would appreciate the guidance from all the teachers at Haichuan
The ethylene content in coker dry gas is caused by excessive cracking; reducing the coking reaction temperature appropriately can help. However, using it as a feedstock for hydrogen production systems will increase the load on those systems and may lead to overheating
It has an impact on the hydrogen production equipment; the olefin content is too high
Reasons: 1. Excessive cracking; 2. Poor stabilization and absorption. Solutions: 1. Reduce the temperature at the outlet of the heating furnace; 2. Decrease the circulation ratio in the distillation tower; 3. Adjust the stabilization process. Hazards: 1. Overheating during hydrogen production (in the case of dry catalytic hydrogen production); 2
