摘要： A process for treating an exhaust gas contaminated with dust, Hg, NOx, and SOx is provided by adding a mercury chlorinating agent, such as, for example, HCl, NH4Cl, or Cl2, and ammonia to the exhaust gas so that the mercury in the exhaust gas is converted to HgCl2. The dust, HgCl2, NOx, NH3, and SOx containing the exhaust gas may then be passed through a reactor containing a catalyst such as, for example, V2O5 and/or MoO3 supported on TiO2, which promotes the reaction between the NOx and NH3 to result in the formation of N2 and H2O. The HgCl2 and SOx containing exhaust gas is then passed through a scrubbing tower where the gas is scrubbed with aqueous solutions of absorbents such as CaCO3 and Ca(OH)2, so that HgCl2 and SOx are removed from the exhaust gas. The cleaned exhaust gas is discharged through a stack.
