The sulfur content in the amine solution is high after its regeneration

As the title suggests, our hydrogenation unit is equipped with a system for treating acidic water gases and regenerating amine solutions. Currently, the pressure at the top of the amine regeneration system is controlled at 0.08 MPa, the temperature at the bottom of the tower is maintained between 120–122°C, while the temperature at the top of the tower is between 100–103°C. After regeneration, the sulfur content in the amine solution is around 2000 ppm. Could anyone please let me know if this level is normal? If it’s not working properly, what needs to be adjusted? Thank you all again.
