| Abstract: | Based on production of S-based compound fertilizer,the factors affecting N use efficiency are discussed on operation conditions(neutralization degree,drying temperature,mixed acid density,product return ratio),N content control in product,raw materials ratio(the amount of mixed sulfuric and phosphoric acids,and the ratio of ammonia to urea),impurities in phosphoric acid,moisture in product and steady operation.Some measures and control demands are presented. |
