Method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas |
摘要 |
<p>This invention relates to a method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas which comprises adding an SO3-decreasing agent (hydrogen gas) to combustion exhaust gas and thereby reducing sulfuric acid (H2SO4) and sulfuric anhydride (SO3) present in the combustion exhaust gas, as well as a combustion exhaust gas flow system therefor. Thus, this invention provides a method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas which can prevent the occurrence of troubles (e.g., low-temperature corrosion and ash deposition) arising from H2SO4, and SO3 contained in combustion gas and which is easy to operate. <IMAGE></p> |
