Question

英语翻译本文比较了氯化钡的几种不同的工艺生产方法,探究以毒重石残液为主要原料,通过真空旋转蒸发结晶氯化钡的工艺方法,得出

Answer 1

This paper compares several methods of production process of barium chloride is different, to explore the witherite residue as the main raw material, process through a vacuum rotary evaporation crystallization of barium chloride, the best experimental conditions that evaporation crystallization, the content of calcium, magnesium, sulfur, iron on the crystallization products of the analysed and discussed. The experimental results show that, the material liquid recycling, barium chloride purity and can meet the requirements of chlor-alkali enterprises. In addition, it explores the sodium sulfide solution corrosion effect on the reactor, the addition of a certain amount of sodium sulfide, at a certain time can protect the reactor is not corroded.
