What is an appropriate temperature to maintain at the bottom of the lift pipe in a catalytic unit?
Thread Content
I would like to ask the experts here about the impact of raising the temperature at the bottom of the lift pipe in the catalytic unit on the reaction and regeneration system, as well as the control techniques involved
It mainly affects the agent-oil ratio; a higher agent-oil ratio results in a higher reaction conversion rate. Attention should be paid to the temperature above the nozzle, as too low a temperature affects the atomization of the feedstock, leading to the formation of unvaporized oil. The adjustment methods include a CRC device to regulate the steam generation from the catalyst cooler, as well as to adjust the temperature in the pre-raising section! Device without CRC adjusts the regenerator bed temperature
