PROCESSES AND PLANTS FOR REDUCING AMMONIA LOSS AND ODOR FROM ORGANIC MATERIAL OR WASTE TO THE ATMOSPHERE

摘要

The invention relates to processes for reducing ammonia loss and odor from organic material or waste to the atmosphere. A plasma generator is applied to upgrade organic waste and manure with a mixture of acidic nitrates and nitrites. The present invention also relates to an acidic nitrate solution, suitable for reducing ammonia loss and odor from organic material or waste to the atmosphere, and a process for producing such an acidic nitrate solution. The invention further comprises plants for reducing ammonia loss and odor from organic material or waste to the atmosphere.

1. A process for reducing ammonia loss and odor from organic material or waste to the atmosphere, comprising
feeding air or contaminated air to an electric arc, electrostatic field, Nano pulsed electric field, dielectric barrier discharged, laser, radio- or micro-wave driven plasma generator, or any combination thereof, to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation; feeding the air containing NOx to an absorber, and absorbing the NOx into an absorption liquid in the absorber to form an acidic nitrogen solution comprising nitrates and nitrites; and feeding the acidic nitrogen solution to the organic material or waste whereby the pH is adjusted to 4-6 and the nitrates and nitrites bind volatile ammonia and ammonia components in or from the organic material or waste, as ammonium nitrate and nitrite salts.
