摘　　要：通过对尿素水溶液吸收SO2能力的机理研究发现,尿素水溶液在常温下(<60℃)对SO2的吸收主要是物理吸收,而化学吸收受到尿素水解速率的控制,达到平衡后,其吸收效率在20%左右。According to the mechanism study of the SO2 absorption by urea solution,it was found that when temperature was low than 60℃, physical absorption was the main aspect, and chemical absorption was influenced by the urea hydrolyze rate,when rate reaches to balance,the absorption efficiency was twenty percent.
