Is the temperature of sulfur-containing methanol exiting the bottom of the absorption tower lower than that of sulfur-free methanol exiting the same tower?

Why is the temperature of sulfur-containing methanol leaving the bottom of the absorption tower lower than that of sulfur-free methanol leaving the same tower? Is it because the heat released by sulfur-free methanol absorbing hydrogen sulfide is lower than the amount of cold energy carried by the process gas entering the absorption tower?
The heat of solution for hydrogen sulfide must be greater than that for carbon dioxide
I agree with you; in the desulfurization stage, it is essentially a phase where the feed gas is used to cool the methanol
