Problem of high temperature at the top of the regeneration tower
Thread Content
I would like to ask everyone for advice: our plant processes around 100,000 cubic meters of fluid per day. The flow rate of MDEA is 5–7 cubic meters per day, while the steam supply to the reboiler is 900–1000 Kg/h. The temperature at the top of the regeneration tower is on the high side; it used to be 103±3 ℃ but has gradually increased to 104±6 ℃. Excluding temperature factors, from a process perspective, how can we determine whether a temperature of 104±6 ℃ is normal? Can this temperature be reached?
Try without reducing the steam? Desulfurization quality or regenerated amine solution quality.
I haven’t tried it yet. I mainly want to know whether, from a technical perspective, this temperature can be achieved, and to determine whether the data is accurate or not.

The higher the hydrogen sulfide and carbon dioxide contents in the rich amine feed, the higher the top temperature of the tower, and the lower the regeneration load; simultaneously, the top temperature rises further.
