Differences in the composition of regenerated flue gas and vent gas in Sinopec’s continuous reforming units
Thread Content
Sinopec’s continuous reforming units are of the 2+2 type; during the catalyst regeneration cycle, part of the regenerated flue gas is recycled while another part is vented to the atmosphere. Are these two streams derived from the same flow? Or the two streams discharged from the two parts of the regenerator? What are the differences in chlorine content, water content, and temperature in this portion of the airflow?
To reduce chlorine corrosion in the regenerator and maintain the water-chlorine balance in the system, it is necessary to remove chlorine from the regeneration gas and the vent gas. The original process was alkaline washing, while the current popular method is fixed-bed dechlorination. What are the differences between these two fixed-bed dechlorination operating conditions? Chlorine content, water content, temperature, etc.~
The gas coming out of the top of the regenerator enters the dechlorination tank where it is vented; it does not go into the circulation system as originally designed in the UOP process, because that system absorbs chlorine but also water
