摘要：用N2和H2S的混合气模拟含硫天然气，以铁基脱硫剂为脱硫液，采用超重力旋转填充床（RPB）进行脱除H2S的集约化实验研究，考察了原料气H2S质量浓度、含硫原料气流量、脱硫液流量、温度及RPB转子转速对H2S脱除率的影响。实验结果表明，铁基脱硫剂超重力法脱除H2S的较佳工艺条件为原料气H2S含量14g/m3，原料气流量0.45m3/h，脱硫液流量13.5L/h，脱硫液温度40℃，RPB转子转速1000r/min。在此条件下，H2S脱除率稳定在99.98%以上，脱硫后净化气H2S含量小于2mg/m3。另外，舍弃再生用RPB，采用直接向脱硫富液储槽鼓空气的方法，脱硫剂氧化再生良好，脱硫效果保持不变，且可长时间稳定运行。因此，铁基脱硫剂超重力法脱硫工艺简单、效率高、设备体积小，可实现海洋油气平台天然气或石油伴生气脱硫的集约化，工业化应用前景广阔。

Abstract：The intensive experimental research on the removal of H2S was conducted using a high gravity rotating packed bed（RPB）with iron-based desulfurizer and a mixture of N2 and H2S，which was used to simulate natural gas. The effects of inlet mass concentration of H2S，gas flow rate，desulfurizer flow rate and temperature and RPB rotor speed on removal rate of H2S were investigated.
The optimized experimental conditions using high gravity technology with iron-based desulfurizer were as follows：mass concentration of H2S in feed14g/m3，gas flow rate 0.45m3/h，liquid flow rate
13.5L/h，desulfurizer temperature 40℃，and rotor speed of RPB 1000 r/min. Removal rate of H2S could
reach above 99.98%，and concentration of H2S after desulfurization was lower than 2mg/m3 under the present experimental condition. Oxidation of used iron-based desulfurizer was also studied by bubbling the air into a storage tank instead of another RPB. Oxidation efficiency could be maintained well and
