2015-11-16 · present work is to introduce a new method for the treatment of sulfur dioxide released f rom effluents of the sul-furic acid production units and the production of a mass quantity of hydrogen. This latter is a non-toxic gas whose burning behavior is highly energy producing. In fact, the production of hydrogen is interesting in a sense
Exhaust gas will go to tail gas washing system, and washed by caustic soda. 3)solid waste Mainly, solid waste is sulfur residue from sulfur melting post. After collecting, and sell it to fireworks factories. Keywords: liquid SO 2 technology, liquid SO 2 process, liquid sulfur dioxide production, liquid SO 2 …
Consequently, sulfur dioxide has become the most widespread man-made pollutant. As such, measurements of the gas are often used as an index of air pollution. In the atmosphere, sulfur dioxide is converted to sulfur trioxide (SO 3), which is absorbed by water vapor. When it rains or snows, this acidic moisture falls to the Earth as acid rain.

A process for the recovery of carbon disulfide from a flue gas. A stream of sulfur dioxide is removed from a flue gas and introduced into a first reduction reactor containing a chromium promoted iron oxide alyst where the sulfur dioxide is reduced to carbonyl sulfide. The carbonyl sulfide is introduced into a second reduction reactor which contains an active alumina alyst.
