开发出了有前景的含 SO2 气体净化解决方案。本研究针对最大化 HPA 吸收剂系统脱硫效率的附加效应和吸收剂再生性能进行了实验。结果发现，所有添加剂包括 NaCl、H3PO4、MnSO4、CuSO4、ZnSO4 和 NH4VO3 对提高 HPA 溶液的脱硫效率具有积极作用。其中，以氯化钠的影响最为显着。发现以下两对，即 NaCl 与 H3PO4 以及 Zn2+ 与 Mn2+ 存在相互作用。基于正交实验，得出多组分吸收剂体系中添加剂/HPA的最佳摩尔比。空气流再生 HPA 的过程受操作温度的影响很大，最佳再生温度约为 100 ℃。 51•Ž。单次HPA的脱硫效率在6次吸收-再生循环的长时间运行中表现出良好的重现性。脱硫后得到的单一HPA溶液也可以通过含有NOR的气流进行有效再生，其效果比空气流更好。
promising resolution to SO2 containing gas purification was developed. In this study, experiments were conducted concerning the additive effect for maximizing the desulfurization efficiency of HPA absorbent system and the performance of absorbent regeneration. As a consequence, all additives including NaCl, H3PO4, MnSO4, CuSO4, ZnSO4 and NH4VO3 were found to have positive effects on the improvement of the desulfurization efficiency of HPA solution. Among them, the effect of NaCl is the most significant. The following two couples i.e. NaCl vs H3PO4 and Zn2+ vs Mn2+, were found to have interactions. Based on orthogonal experiments, the optimum additive/HPA molar ratio in multi-component absorbent system was gained. The process of HPA regeneration by air stream is strongly influenced by operation temperature, whereby the optimum regeneration temperature was found to be ca. 51•Ž. The desulfurization efficiency of single HPA shows excellent reproducibility during long time operation of 6 absorption-regeneration cycles. The resultant solution of single HPA after desulfurization can also be effectively regenerated by gas stream containing NOR, which shows better effect than that by air stream.
