High concentrations of CO₂ compete with H₂S for absorption in the alkaline absorbent solution, consuming the available alkalinity and lowering the pH of the solution. This disrupts the balance of the core process in the wet oxidation method, which involves \"alkaline absorption followed by oxidative regeneration\", leading to a series of problems throughout the entire process. As a result, the desulfurization efficiency declines, operating costs increase significantly, and equipment failures become more frequent. I. Key Impacts: Absorption stage – The dose-effect advantage of CO₂ reduces effective alkalinity, thereby lowering the pH of the solution
