| 摘 要： | 利用聚丙烯中空纤维膜组件为吸收器,甲基二乙醇胺作为液态吸收剂,采用多级级联的工艺,以含硫天然气为研究体系,研究了吸收液流量和压力与原料气的流量和压力对传质系数和H2S脱除率的影响。与传统的脱硫方法相比,投资费用减少40%,运行费用减少30%。研究结果表明:多级膜吸收技术脱硫效率可以达到95%以上,且随着吸收液流量的增大而增大;可将硫含量控制在2.5 mg/m3以下,达到输送或使用标准。

| Abstract: | Using polypropylene fibre as absorber and methyldiethanolamine(MDEA) as absorbent.H2S was treated by multistep membrane absorption technology.The influence of some factors on desulfurization efficiency was studied,such as gas pressure difference between membrane,velocity of flow,flow ratio.The membrane absorption technology is normally associated with lower capital and operating costs than the traditional method.The experiment results showed that membrane absorption technology can purify natural gas by removing sulfur and control sulfur content less than 2.5 mg/m3. |
