EAC-4 SO2fine desulfurizer can be used for fine desulfurization in production processes such as ammonia synthesis, methanol, methanol synthesis, methanization, fuel production, and food CO2. It can also be used for fine desulfurization of city gas, water gas, coke oven gas, natural gas, etc. EAC-4 fine desulfurizer has a high sulfur capacity for SO22(0.05ppm) at room temperature.

II. Reaction Principle and Quality Inspection Standards
1. Reaction principle
The H2S and SO2in the feed gas react with the remaining O2to form sulfur deposits in the micro scale.

III. Normal Operation and Usage Conditions
(1) Airspeed: H2S, SO2≤ When 10mgS/NM3, the airspeed is around 1000-1, H2S、SO2≥ 10mgS/NM3， Airspeed of 5000-800 h-1.
(2) The temperature ranges from 5 to 8.0 MPa.
(3) Pressure: normal pressure~8.0Mpa.
(4) Humidity: When removing H2S and SO2, the higher the humidity, the better, preferably close to saturated water vapor, but it is strictly prohibited to bring water into the bed.
(5) O2content: O2is necessary for the removal of hydrogen sulfide by activated carbon. In theory, O2/H2S≥ 0.5 is sufficient. In actual operation, O2/H2S≥ 3 is good, the general process gas can meet the requirements.
