| Abstract: | To recover a highly-concentrated ammonia/nitrogen condensate from vacuum buffer tank for crystalline ammonium nitrate and have it introduced together with cooling fluid of ammonium nitrate into an electro-dialysis membrane treatment facility and after being treated the concentrated solution of ammonium nitrate is routed into the system for crystalline ammonium nitrate for re-use ,the fresh water with the concentration of ammonia/nitrogen not over 40mg/L is recycled to circulation water system to reach the goal of energysaving and emission-reduction, environment protection. |
