The Qualification of Mingsheng Ammonia flue gas desulfurization(FGD)
Ammonia is used as desulphurizer in ammonia desulfurization process with low electricity consumption and low water consumption. The desulphurizer comes from a wide range of sources and has no waste water, waste gas and three wastes. Ammonium sulfate by-product can be used as sulfur-based chemical fertilizer. It is a green and non-pollution-free environmental technology.
