【摘要】 以柠檬酸 柠檬酸钠溶液为缓冲液在高效规整填料塔中进行烟气脱硫。模拟的烟气首先在吸收塔中用柠檬酸钠溶液脱硫 ,然后富液在解吸塔中释放出SO2 ,再生的缓冲液返回吸收塔循环使用。研究了影响吸收及解吸效率的各种重要参数 ,确定了最佳操作条件。对解决SO2 污染问题提供了应用基础更多还原

【Abstract】 FGD process using citric acid / sodium citrate buffer solution has been carried out in structured packing columns.SO 2 in analog flue gas was first absorbed in aqueous sodium citrate solution in an absorption column and then recovered from the loaded solution in a desorption column.The regenerative buffer solution circulated to absorption column again for use.Several important factors that may affect SO 2 absorption and desorption efficiency were tested individually.The optimal operating conditions for sodium citrate FGD process in pilot packing columns were determined,which can be extended into large scale FGD design.更多还原
