    摘要: A method for removing sulfur dioxide from waste gases by a wet oxidation-absorption method, which is characterized in that an aqueous solution of ammonium sulfate acidified with sulfuric acid at a pH range of 3 - 4 is used as the absorbent. The SO.sub.2 contained in the waste gases is absorbed with the aqueous solution of ammonium sulfate in an absorption tower and then oxidized with air or oxygen to be converted into sulfuric acid in an oxidation tower.

    摘要: Apparatus for treating exhaust gases comprising a catalyst bed through which the exhaust gas is passed whereby nitrogen oxides and dust present therein are removed from the gas, said catalyst bed being designed such that the catalyst therein is discharged from the bed continuously or intermittantly while being fed in an amount that can compensate for the discharged amount, a heating device for heating the catalyst discharged from the bed to a temperature in a range from about 700.degree. to 1200.degree. C. for reactivation of the catalyst and separation of the dust accumulated on the bed surface and retained in the interstices between the catalyst particles therein, and a device for discharging sulfur dioxides produced during the course of heating the catalyst. This apparatus is very effective in simultaneously removing the nitrogen oxides and the dust from exhaust gases such as boiler exhaust gases.

    摘要: The object of this invention is to provide a method for mitigating a stress corrosion cracking of reactor structural material which makes it possible to suppress the rise in the main steam line dose rate without secondary effects such as a rise in the concentration of radioactive cobalt-60, etc. in the reactor water. Hydrogen and a reductive nitrogen compound containing nitrogen having a negative oxidation number (for example, hydrazine) are injected into the core water of boiling water nuclear power plant. By injecting the reductive nitrogen compound containing nitrogen having a negative oxidation number into the core water, the stress corrosion cracking of structural material of reactor can be mitigated without side reactions such as a rise in the concentration of cobalt-60, etc.
