摘要：

Experiments were carried out using nanofiltration to separate salts from a hydrogen sulphide scrubber solution taken from an iron-based liquid-redox process. The scrubber solution used in these experiments contained organic chelating agents, iron, and various alkali metal inorganic salts (i.e., sulphates, thiosulphates, carbonates, and bicarbonates). The nanofiltration unit was equipped with monovalent ion-selective membranes. Results indicated that the nanofiltration membranes retained organic materials and iron and allowed ionic species (e.g., SO42-, S2O3-, CO32-, HCO3-) to permeate. Results also indicated that the nanofiltration membranes used in these experiments preferentially removed CO32- and HCO3- over SO42- and S2O32-. The nanofiltration tests did not show any sign of membrane degradation in terms of ion selectivity; however, at high total-dissolved solids concentrations, the permeate flow rate was reduced.
