我国中低浓度复混肥厂广泛采用尿素、过磷酸钙为原料 ,过磷酸钙一般需要经过氨化处理中和其游离酸。为防止过度氨化 ,碳酸氢铵用量不超过过磷酸钙量的 10 %。传统的氨化方法存在占用大量人力资源及场地 ;反应生成 CO2 逸散 ,造成物料的损失。经过多次试验 ,发现氧化镁是一种省?
China’s low concentration of compound fertilizer plant widely used urea, superphosphate as raw material, generally need to go through ammoniation and free acid. To prevent excessive ammoniation, ammonium bicarbonate dosage does not exceed 10% of the amount of superphosphate. The traditional ammoniation method occupies a large amount of human resources and site; the reaction generates CO2 to escape, resulting in the loss of materials. After many tests and found that magnesium oxide is a province?
