Study on the Process Parameters of Purifying Calcium Nitrite by Lime Cream 用石灰乳提纯亚硝酸钙工艺条件研究
Controlling the heating time for removing NO-2 and inhibiting induced reaction are the main factors affecting the accuracy of determination when using the method of ammonium chloride for the determination of nitrate content in calcium nitrite solution. 氯化铵法测定亚硝酸钙溶液中硝酸根含量时,影响测定结果准确性的因素主要为:加热微沸时间和诱导反应。
Inhibiting Effect of Calcium Nitrite on Rebar Chloride-Attack Corrosion 亚硝酸钙对混凝土结构中钢筋氯腐蚀的缓蚀作用
The result shows that the absorption facts of the former to NOx is higher than the latter, and the lay-product calcium nitrite can be obtained. 在小试装置上做了石灰乳与纯碱溶液的吸收对比实验,结果表明:石狄乳对NOX的吸收效果高于纯碱溶液,并且能够生产出合格的亚硝酸钙产品。
Technological designing of the plant producing calcium nitrite 800t/ a 年产800t亚硝酸钙生产装置工艺设计
Results show that the best dosing of calcium carbonate is 23.81 g, In this alkalinity, ammonia nitrogen conversion realized the highest, and nitrite accumulation rate is higher. 本实验确定出碱度(以碳酸钙计)最佳投加量为:23.81g碳酸钙,在此碱度下,氨氮转化率最高,并且亚硝酸盐积累率较高。
