【Abstract】 Ion membrane electrolyzer is the key equipment for making caustic soda with ion membrane technology method,and one of its technical specification of type selection is the current density.The restriction factors of current density and the effect of the current density on ion exchange membrane electrolyzer cost have integrated analyzed by considering the relationship of current density and NaOH purity.In recent years,5.0~5.5kA/m2 current density range is regarded as the appropriate chosen,while the DC power consumption range is 2150~2200kWh/t NaOH.更多还原
