Abstract

Sodium sulfate, sodium nitrate, ammonium lactate and sodium glycinate were converted to original acids and bases by means of Bipolar membrane electro-dialysis.<BR>Sodium sulfate and sodium nitrate were subjected to 3-compartment Bipolar membrane (BPM/CM/AM) electrodialysis. When the concentration of acid and base increased, the current efficiency decreased and the salt content increased. Energy consumption of NaOH production was 2300kwh/t-NaOH.<BR>In the case of sodium nitrate, the results were very similar to those for sodium sulfate. Ammonium lactate and sodium glycinate were subjected to 2-compartment Bipolar membrane (BPM/CM) electrodialysis. Ammonium lactate was converted to lactic acid by more than 99%. Energy consumption was 0.61kwh/kgLacH. Sodium glycinate was converted to glycine by 95%. Energy consumption was 0.78kwh/kg Glycine.<BR>Ammonium lactate was subjected to 2-compartment Bipolar membrane (BPM/AM) electrodialysis. Ammonium lactate was converted to Lactic acid by more than 98%. Concentration of lactic acid reached 3.5mol/<I>l</I> and energy consumption was 0.83kwh/kgLacH.
