Hydrogen sulfide levels remain high behind the tower

It deals with desulfurization in a coking Claus furnace; the gas flow rate is around 30,000 units, the circulation rate of the desulfurization liquid is 130 cubic meters per hour. The temperature at the top of the regeneration tower is 52–55 degrees, while the temperature at the bottom is 59–61 degrees. The vacuum level is between -84 and -86 kPa, and it is -80 to -83 kPa at the bottom of the tower. The lean liquid contains approximately 1.8% hydrogen sulfide, while the rich liquid contains about 3.0% hydrogen sulfide. The salt content is 8, and the total potassium content is 55–60. The hydrogen sulfide level after the desulfurization tower remains between 500 and 800 units. I would appreciate advice from experienced colleagues.
The lean liquid contains 1.8% hydrogen sulfide, which is on the high side
What is the feed temperature of the lean amine solution?
What is the desulfurization process? Vacuum potassium carbonate?
