Because blast furnace gas contains organic sulfur, H2S and other impurities, if blast furnace gas is used as fuel, the SO2 in the flue gas does not meet emission standards. There are two main measures to reduce emissions: blast furnace gas desulfurization or exhaust flue gas desulfurization.
Description of technology
Because blast furnace gas contains organic sulfur, H2S and other impurities, if blast furnace gas is used as fuel, the SO2 in the flue gas does not meet emission standards. There are two main measures to reduce emissions: blast furnace gas desulfurization or exhaust flue gas desulfurization.
Blast furnace gas contains H2S and organic sulfur (mainly COS), and to achieve emission targets the organic sulfur must be converted to H2S and then the H2S removed.
Installation scale: 5000~500000nm³/h.
Specifications
1.Organic sulfur conversion rate is high, can reach 90 - 95%;
2.The device has a small pressure drop, which does not affect the power generation of TRT blast gas;
3.The device occupies a small area and is suitable for the reconstruction of an established steel plant.
Applications
Project for desulfurization of blast furnace gas or other gas containing organic sulfur.
