Environmental Protection Engineering

The low-temperature industrial flue gas simultaneous desulfurization, denitrification and dust removal technology, based on the traditional circulating fluidized bed semi-dry desulfurization process, incorporates a low-temperature catalyst. By rationally controlling the process steps and operating parameters, through free radical reaction, under the action of sulfur dioxide and oxygen, nitric oxide is first oxidized to nitrogen dioxide, and then together with sulfur dioxide is absorbed by the absorbent Ga(OH)2 or GaO, thus achieving the goal of simultaneous desulfurization and denitrification.
