Abstract
Systems and methods for producing an organic fertilizer rich in humic substances and nitrogen from waste gases and liquids are disclosed. The methods include forming a mixture of coal and liquid and contacting said mixture with a gas containing ammonia, allowing ammonia react with the coal to release humic substances to the liquid and to complex ammonia with the coal and humic substances controlling the pH of the mixture and forming a humic ammonia rich fertilizer. The systems include a mixing chamber fluidly connected to sources of liquid and coal, a gas contacting chamber, a pH control subsystem, a solid liquid separator and a pathogen deactivator.
Claims20
A method of making a fertilizer product, the method comprising:
- combining coal solids with a liquid to form a coal-liquid stream;
- mixing the coal-liquid stream to suspend the coal solids in the coal-liquid stream;
- contacting a gas stream containing ammonia with the coal-liquid stream to absorb ammonia into the coal-liquid stream and form a coal-ammonia slurry;
- and
- collecting the coal-ammonia slurry as the fertilizer product.
A method of making a fertilizer product, the method comprising:
- introducing coal solids comprising metal humates into a reactor;
- introducing a nitrogenous liquid comprising ammonia into the reactor to form a coal-liquid stream;
- mixing the coal-liquid stream to suspend the coal solids in the coal-liquid stream;
- controlling a rate of introducing the coal solids into the reactor to control pH of the coal-liquid stream and stabilize the ammonia forming a coal-ammonia slurry;
- and
- collecting the coal-ammonia slurry as the fertilizer product.
