Bottom temperature of catalytic regeneration tower

The bottom temperature of the regeneration tower is an A-class parameter, to be controlled between 110 and 130 degrees Celsius. There are two A-class parameters in total for distillation; the other one is the bottom temperature of the fractionation tower, which is controlled to prevent coking of the slurry. Is bottom temperature control in the regeneration tower that important? Is it closely related to the physical properties of ethanolamine, or are there other factors as well?
MDEA undergoes thermal degradation at temperatures above 127°C, producing thermally stable salts; this not only causes erosion and corrosion of equipment and pipelines but also increases solvent loss.
