1. utilize process of desulfurization for boiler flue gas to process a method for sulfur recovery tail gas, said method comprising the steps of:

  • (1) sulfur recovery tail gas is burned, wherein, the sulfide in sulfur recovery tail gas is converted into sulfur dioxide;

    (2) sulfur recovery tail gas after making to burn is converged formation with boiler smoke and is converged flue gas, converges flue gas and enters in ,

    absorption tower, absorption tower, converges flue gas and discharges after absorption liquid counter-current absorption;

    Wherein, described absorption liquid is the aqueous solution that contains ammonium salt, and described ammonium salt is the mixture of ammonium sulfate and ammonium sulfite.
