AI Technical Summary
Existing technologies have low hydrogen sulfide removal efficiency and insufficient sulfur absorption under high temperature conditions. Furthermore, the desulfurizing agents are not heat-resistant, resulting in complex processes, large equipment investments, and high operating and maintenance costs.
A liquid-phase desulfurizing agent comprising ionic liquid, metal chelate and water solvent is used. The metal chelate solution is prepared under conditions of pH 7-9 and mixed with ionic liquid. The resulting desulfurizing agent has high sulfur absorption capacity and high desulfurization efficiency at high temperature.
It achieves efficient absorption and removal of hydrogen sulfide under high temperature conditions, improves the stability of the desulfurizing agent and the sulfur absorption capacity, simplifies the process flow, and reduces equipment investment and operation and maintenance costs.
