| titleOfInvention | Wet treatment of petroleum-based combustion ash |
| abstract | (57) Abstract: A method for wet treatment of combustion ash containing at least ammonium sulfate and magnesium, comprising a slurry preparation step of mixing the combustion ash with water, a double decomposition step of ammonium sulfate, and the double decomposition In the step of recovering the free ammonia from the slurry containing gypsum and free ammonia generated in the step, and in the ammonia recovery step in a wet process that sequentially includes the gypsum separation step, the stripping efficiency of ammonia from the gypsum slurry is excellent, In addition, the present invention provides a method for wet treatment of petroleum-based combustion ash in which blockage of the stripping device is suppressed. In the ammonia recovery step, the slurry is allowed to flow down from above using a packed tower, and air or steam is blown from below to make countercurrent contact with the slurry to strip ammonia. |
