How does the hydrogen sulfide concentration of the gas entering the absorption tower affect the steam consumption in the regeneration tower?

When the hydrogen sulfide concentration of the gas entering the absorption tower is high, more amine solution is absorbed; as a result, the H2S concentration in the enriched amine solution increases, and more steam is required for thermal desorption

To meet the requirement that the H2S content at the outlet of the absorption tower be less than 300 ppm, the amount of amine solution required may also need to increase

Obviously, a higher hydrogen sulfide content requires more regenerated amine solution
