| titleOfInvention |
A wet-processing method for combustion ashes of petroleum fuels, containing ammonium sulfate and a method of utilizing ammonia components recovered by the wet-processing method |
| abstract |
The present invention relates to a wet-processingnmethod which comprises at least a preparing-step of a slurrynof combustion ashes of mixing combustion ashes and water, andouble decomposition step for ammonium sulfate, a recovering-stepnof free ammonia from a gypsum slurry containing freenammonia produced in the double decomposition step and angypsum separation step successively, which is excellent in annammonia stripping efficiency from the gypsum slurry in thenammonia recovery step and in which the clogging in anstripping device is suppressed, as well as a method ofnutilizing ammonia components with an industrial advantage. |
