| 摘 要： | 用N2、H2S模拟含硫天然气,研究了常压下超重力反应器中,二乙醇胺(DEA)和N-甲基二乙醇胺(MDEA)溶剂的脱硫性能。分别考察了液量、气速、转速、H2S体积分数以及温度对2种溶剂脱硫性能的影响。结果表明:采用质量分数为20%的DEA脱硫剂,在常温、转速为1000 r/min、液量为3.5 L/h、气速为910 L/h、进口H2S体积分数为1%的条件下,获得了99.9%的脱除率。与MDEA比较,在相同的操作条件下,DEA的脱硫效果优于MDEA。

| Abstract: | An experimental study of the absorption of H2S from gaseous mixtures of N2 and H2S(used as a model for natural gas) by aqueous solutions of diethanolamine(DEA) and N-methyldiethanolamine(MDEA) in a rotating packed bed(RPB) has been carried out.The effects on H2S removal efficiency of varying the liquid flow rate,gas flow rate,rotation speed,sulfur concentration and temperature were investigated.The results showed that a desulfurizer containing an aqueous solution with mass fraction of DEA of 20% had a high ... |
