Bayer Red Mud To Absorb Sulfur Dioxide

The sulphur content of the our country coal is higher, the high sulphur coal of the southwest region attain to more than 2/3, the technology on removal of industry waste-gas SO₂ is inevitable. But in alumina production, production of 1 ton alumina will produce about 0. 7¹. 4 ton red mud, several big aluminum factories of our country produce about ten million ton of red mud annually. Handling this wastes will spend a great deal of funds, the pollution of the red mud for environment is serious at the same time, the main performance is that the red mud of outside can't wash clear easily ; Fluid matter with alkali liquid seep through the ground , polluting surroundings; A lot of farmlands was taken up .Currently ,on account of the cost of circulation is too high , the technology on removal of industry waste-gas SO₂ is difficult to circulate.It has been reviewed for the introduction of the domestic and international the technology on removal of industry waste-gas SO₂ . using the discarded red mud of alumina production in great quantities take off the the waste gas of SO₂ in Thermodynamic analyze, the circulating absorption experiment of kinetics at the laboratory carries on in the small scaled absorbed tower .filler, combine, the absorption temperature, the drum breeze quantity, the pH value, circulating discharge, import the...
