摘要: 提出了一种有机胺吸收二氧化硫的烟气脱硫工艺.采用填充柱常压吸收常压再生操作流程,以解吸率和有效吸收SO2容量为评价指标,研究了哌嗪水溶液的脱硫性能,并将其与甲基二乙醇胺(MDEA)和乙二胺(EA)溶液作了比较.实验表明,0.3—0.5mol·l-1的哌嗪水溶液在30℃的温度下能达到较佳的吸收效果,而在85℃的温度下解吸能有效地减少富液挥发损失并达到95%以上的解吸率.哌嗪水溶液的单位有效脱硫容量达到了3.49g·g-1,远高于MDEA和EA.

Abstract: A flue gas desulfurization(FGD)process was proposed,in which organic amine is used as absorbent to absorb the sulfur dioxide in flue gas.Using a packed column at atmospheric pressure,absorption performance of aqueous piperazine was studied and compared with MDEA and EA in terms of desorption rate and effective absorption capacity of SO2.The results show that 0.3—0.5mol·l-1 piperazine provides good absorption at 30℃,and achieves a desorption rate up to 95% at 85℃ and meanwhile reduces the loss rate of feed-in solution.It shows that the effective desulfurization capacity of aqueous piperazine reaches 3.49g·g-1,which is much higher than MDEA and EA.
