1. Increase steam consumption 2. Reduce feed amount
By adjusting the reboiler outlet temperature； Flow rate of stripping steam ； Temperature of the stripping steam.
It is controlled by the feed heater of the fractionation tower.
Reaction temperature adjustment； Adjustment of slurry circulation volume ； Mid-stage circulation volume adjustment ；
Adjust the gas flow rate to the fractionation tower; adjusting the reflux flow rate is not recommended. Adjust the heat transfer capacity of the feed heat exchanger
Generally, the bottom temperature of the distillation tower is adjusted using the amount of slurry returning to the tower
By adjusting the reboiler outlet temperature； Flow rate of stripping steam ； Temperature of the stripping steam
Adjust the temperature of the fractionator and the amount of material drawn off
Control the heat to the reboiler and the operating pressure of the tower
Feed temperature, reboiler temperature of the column
