Extraction and Preparation of Sulfur
Sulfur is a non-metal chemical element that is represented with the chemical symbol "S" and the atomic number 16 on the periodic table. Sulfur is a yellow non-metal that melts at 130 °C ...
Conversion of Sulfur to Sulfur Dioxide S → SO2
Sulfur used in Caspian sulfuric acid plant has a purity of 99.8%. Sulfur is first charged by a loader into smelting pools. In this part, sulfur is melted in contact with steel coils that have reached ...
Conversion of Sulfur Dioxide to Sulfur Trioxide SO2 → SO3
After the molten sulfur is descaled in the sedimentation ponds, it is time for SO2 gas, which firstly its temperature is reduced by passing through a 13-ton boiler and passing through a tank called a ...
After leaving the converter, SO3 gas is directed to the three absorption towers. In absorption towers, SO3 reacts with sulfuric acid that escapes from all-steel acid showers embedded inside the ...
Another noteworthy point is that the weight of the load is determined in the control room and then loading is done by fully automatic devices without manual intervention, under the supervision of the ...
