Method for producing ammonia from solution containing ammonium nitrogen for producing nitrogenous compounds like nitric acid, urea, nitrogen fertilizers, and for pre-products of plastics, involves pulse impressing solution

摘要

Ammonia production involves pulse impressing the solution. The frequency of solution is determined on the natural frequency in the gas bubbles or vibrating particles contained in the effluent. The treatment of the solution is carried out at an pH value of 6-11, and 40-90[deg] C temperature under vacuum.
