Abstract: A system for converting sodium sulfate ore into chemicals of which H.sub.2 SO.sub.4 and Na.sub.2 CO.sub.3 are examples, utilizing a membrane process, the basic electrodialysis cell of which is located, usually as a series of such cells, between cathode and anode compartments. Each cell constitutes a pair of cation permselective membranes between which a bi-polar membrane is disposed in spaced relationship thereto with the cation permselective face thereof confronting the cation permselective membrane and the anion permselective face thereof facing the other cation permselective membrane. The cation permselective membranes of adjacent cells are common to such adjacent cells. All of the cation permselective faces of the bi-polar membranes face the cathode electrode and all of the anion permselective faces of the bi-polar membranes face the anode electrode. Each cell includes a base zone and an acid zone. Each acid zone is defined by a cation permselective membrane and the confronting cation permselective face of the bi-polar membrane and each base zone is defined by a cation permselective membrane and the confronting anion permselective face of the same bi-polar membrane. The acid zone is fed by a water solution of a sodium salt, for example Na.sub.2 SO.sub.4 and Na.sub.2 S and the base zone is fed by a saturated water solution of NaHCO.sub.3 or by a water solution of a mixture of NaHCO.sub.3 and Na.sub.2 CO.sub.3 or by a mixture of a water solution of Na.sub.2 CO.sub.3 and CO.sub.2 which reacts with the Na.sub.2 CO.sub.3 to form NaHCO.sub.3. The feeding of these composite solutions to the different zones results in increased current efficiencies by removing free H.sup.+ ions from the acid zone and free OH.sup.- ions from the base zone. The cathode and anode electrodes are disposed in respective compartments through which water solutions of NaOH circulate. The cell is part of a plant in which other treatments are performed.
Abstract translation: 将硫酸钠矿石转化为H2SO4和Na2CO3的化学物质的系统是利用膜工艺，其基本电渗析池通常在阴极室和阳极室之间作为一系列这样的电池。 每个单元构成一对阳离子选择选择膜，在该阳离子选择选择膜之间设置双极膜，其中阳离子选择选择面与阳离子选择选择膜及其阴离子选择选择面面向另一个阳离子选择渗透膜。 相邻细胞的阳离子选择性膜对于这种相邻细胞是常见的。 双极膜的所有阳离子选择面都面向阴极，双极膜的所有阴离子选择选择面都面向阳极电极。 每个电池包括基极区和酸性区。 每个酸性区域由阳离子选择性膜定义，并且双极膜和每个基区的相对阳离子选择面由阳离子选择性膜和相同双极膜的相对阴离子选择性表面限定。 酸性区域由钠盐的水溶液（例如Na 2 SO 4和Na 2 S）进料，碱性区域由饱和NaHCO 3水溶液或NaHCO 3和Na 2 CO 3的混合物的水溶液或由 Na2CO3和CO2的水溶液，与Na2CO3反应生成NaHCO 3。 将这些复合溶液进料到不同的区域通过从酸性区域除去游离的H +离子并从基区域释放游离的OH-离子而导致提高的电流效率。 阴极电极和阳极电极设置在相应的室中，NaOH水溶液通过这些隔室循环。 细胞是进行其他处理的植物的一部分。
