Process for treating effluent gas.

摘要

A process for treating an effluent gas which includes the steps of leading an effluent gas containing sulfur oxides (SOx) and/or nitrogen oxides (NOx) to a radiation irradiation zone, adding ammonia (NH3) to the effluent gas before, during or after the irradiation, collecting resulting ammonium sulfate and/or ammonium nitrate by means of a dust collector, and releasing the effluent gas into the atmosphere. The desulfurization and/or denitration rate is improved by using as the dust collector a bag filter alone or a combination of an electrostatic precipitator and a bag filter, and adjusting the effluent gas temperature at the outlet of the bag filter within the range of from a temperature at which the humidity of the effluent gas is saturated to 100 DEG C.
