<p>PROBLEM TO BE SOLVED: To desulfurize efficiently a gas containing a sulfur content by a method wherein a gas containing a sulfur content is desulfurized by a desulfurizing agent, and the used desulfurizing agent is regenerated in a regenerating tower to be used again for desulfurization, a desulfurizing pipe for desulfurizing the gas by allowing the gas and the desulfurizing agent to flow in a flow channel is provided in the regenerating tower. SOLUTION: Desulfurizing equipment 30 is equipped with a desulfurizing pipe 3 for desulfurizing by introducing a gasified gas from a gasified gas introducing line 2 to be allowed to flow together with a desulfurizing agent. Then, a gas exhausted through a refined gas exhausting line 4 from the desulfurizing pipe 3 is separated from the desulfurizing agent with a particle separator 5, and the desulfurizing agent from which a gas content is separated is introduced into a regenerating tower 1 through a desulfurizing agent returning line 6 to be regenerated with a regenerating gas. Then, the regenerated desulfurizing agent is returned to flow to the gasified gas duct line 2 with a desulfurizing agent supply line 7. The regenerating gas sent into the regenerating tower 1 with a regenerating gas circulating line 9 is exhausted from a top part of the regenerating tower 1 as a gas containing highly concentrated SO2 after executing a regeneration treatment of the desulfurizing agent.</p> |
