Na_2CO_3-NaHCO_3-Na_2SO_4(NaCl)-H_2O体系相图在天然碱湖卤水生产小苏打工艺计算中的应用

Application of the Phase Diagram of Na 2CO 3-NaHCO 3-Na 2SO 4(NaCl)-H 2O System in Process Calculation for Manufacturing Sodium Bicarbonate from Brine of Natural Soda Lake

本文利用Ｎａ２ＣＯ３－ＮａＨＣＯ３－Ｎａ２ＳＯ４（ＮａＣｌ）－Ｈ２Ｏ体系相图对内蒙古合同查汉淖尔碱湖卤水碳化法生产小苏打进行了相图计算，并对计算结果进行了讨论。

Using the phase diagram of Na 2CO 3-NaHCO 3-Na 2SO 4(NaCl)-H 2O system,phase diagram calculation was made for the carbonization process to manufacture sodium bicarbonate from brines of natural soda lake of Inner Mogolia by carbonization process and the calculation results are discussed in the paper.
