The problem of reformation replacement gas
Thread Content
What are the requirements for the temperature of the replacement gas? What are the requirements regarding traffic volume? Is it necessary to make adjustments if regeneration is stopped for an extended period of time?
The temperature of the regenerated replacement gas is generally controlled at around 180°C, which is also related to the material of the equipment. Just control the process parameters related to traffic safety. Regenerative stopping can raise the temperature to 200°C.
Temperature 175, flow rate 600. During regeneration and shutdown, the temperature of the purge gas should be increased. I’ve experienced insufficient purging, which resulted in oil-contaminated catalyst entering the dust collector
Why is the temperature increased after regenerative braking? Is it to prevent heavy oil and gas from aggregating?
During regeneration shutdown, the catalyst does not flow; do you mean that restarting regeneration is what carries the oil and gas to the separation hopper? Personally, I think it’s due to heavy oil and gas condensation?
Primarily, oil and gas accumulate in the catalyst collector, causing the catalysts to stick together and affecting lifting
I would like to ask about the hazards, symptoms, and remedies associated with catalyst carrying oil and gas into the separation hopper Could you share it? Thank you
