Sodium Chlorate → Sodium;chloric acid;chlorate

Table 10 shows the net average overall throughput rates and concentrations of products obtained in this experiment. Slightly diluted purified sulfuric acid from the GAP system of Example 1 (173 g/L H2SO4 and 22 g/L Na2SO4) was fed to the DCU component (sodium form) of the DPU at a feed rate of 2.5 L/h thereby converting the DCU to the hydrogen form and producing a sodium sulfate-rich regeneration product (64 g/L Na2SO4 and 8 g/L H2SO4 with 8 g/L residual NaClO3) at 2.7 L/h. In a subsequent step, a concentrated sodium chlorate solution (669 g/L NaClO3) was fed to the DCU component (hydrogen form) of the DPU at 1.2 L/h thereby producing a sodium chlorate/chloric acid mixture (260 g/L NaClO3 and 140 g/L HClO3) at a rate of 1.7 L/h. The IT obtained was 1.21.
