  • Process for reducing sulfur emission of sulfur plant
    Patent number: 8871176
    Abstract: The present invention provides a process for reducing sulfur emission of a sulfur plant, wherein the sulfur plant includes a thermal reaction unit, a catalytic reaction unit and a tail-gas purification unit, the process is characterized in that the waste-gas from the degassing of the liquid sulfur in the liquid sulfur tank is introduced into the catalytic reaction unit, and/or the waste-gas from the degassing of the liquid sulfur in the liquid sulfur tank is introduced into the tail-gas purification unit. In present invention, the H2S in purified tail-gas can be reduced to no more than 10 ppm(v) and the SO2 emission concentration of the sulfur plant can be reduced to no more than 100 mg/m3.
