Research on Additive and Its Content When Magnesium Slag as Substitute of Limestone 镁渣替代石灰石配料外加剂的选择及掺量的研究
Sodium sulfate, magnesium sulfate, and sodium humate can all effectively improve mass transfer characteristics of the slurries. Compared with the limestone FGD process without additives at the same reaction time, the mass transfer coefficients of additive-enhanced process are effectively increased; 硫酸钠、硫酸镁和腐殖酸钠均能有效地改善浆液的传质性能,与非强化过程相比,反应时间相同时,添加剂强化过程的传质系数大幅度提高;
Effects of magnesium sulfate on wet limestone FGD process 硫酸镁对湿式石灰石烟气脱硫过程的影响研究
Substituting magnesium slag for limestone to produce Portland cement clinker 镁渣替代石灰石配料烧制硅酸盐水泥熟料
The method is applied for the determination of magnesium in limestone with relative standard deviation of less than 3.0% and recoveries of adding standard of 98.4%-101.6%. 测定结果的相对偏差为1·23%,相对标准偏差小于3·0%,其加标回收率为98·4%~101·6%。
And that adding magnesium sulfate could promote the dissolution rate of limestone/ lime, slow down the descent of pH value, achieve higher SO2 removal efficiency at the same pH value and therefor increase limestone/ lime utilization. 添加硫酸镁能促进石灰石/石灰的溶解,延缓pH值的降低,在相同pH值下又能有效提高脱硫率,故可提高石灰石/石灰的利用率。
This paper describes the process in detail of mixing and burning to produce high magnesium metallurgical lime in shaft kiln with the material of limestone and dolomite. 介绍了以石灰石和白云石作原料在坚窑中混烧试制高镁冶金石灰的具体过程。
The promoting effects of sodium sulfate, magnesium sulfate and sodium humate on limestone dissolution in flue gas desulfurization ( FGD) process were studied in a stirred tank. 以双搅拌釜为实验设备,研究了烟气脱硫过程中硫酸钠、硫酸镁和腐殖酸钠对石灰石的促溶作用。
The method is accurate and simple. It has been applied to determine calcium and magnesium in tap water and limestone. 将其应用于自来水和石灰石中钙镁的测定,结果可达到化学分析准确度的要求。对批量样品的分析具有省时省力的特点,是很有应用前景的方法。
