　　The methane recovery rate of single-stage membrane separation is relatively low (usually 90%~95%), and multi-stage series connection or combination with other technologies (such as PSA) is needed to improve the recovery rate.

　　产品纯度受限

　　Product purity is limited

　　单一膜分离难以直接达到高纯度（如>98% CH?），可能需要二次提纯。

　　Single membrane separation is difficult to directly achieve high purity (such as>98% CH?), and secondary purification may be required.

　　CO?渗透侧的甲烷残留需循环处理，增加复杂度。

　　The residual methane on the CO permeation side needs to be recycled, increasing complexity.

　　工艺条件要求严格

　　Strict process conditions are required

　　需稳定控制压力、温度和流量，否则分离效率下降。

　　Stable control of pressure, temperature, and flow rate is required, otherwise the separation efficiency will decrease.

　　高压操作（通常20~40 bar）对设备密封性要求高。

　　High pressure operation (usually 20~40 bar) requires high equipment sealing.

　　适用场景推荐使用：中小型蘑菇视频在线观看项目（100~1000 Nm?/h）、杂质含量较低的蘑菇视频在线观看源、对能耗敏感的场景。

　　Recommended application scenarioses: small and medium-sized biogas projects (100-1000 Nm?/h), biogas sources with low impurity content, and energy sensitive scenarioses.

　　慎用或需改进：高杂质（如H?S>500 ppm）、大规模项目（需多级膜系统）、要求CH?纯度>99%的情况。

　　Caution or improvement needed: high impurities (such as H2S>500 ppm), large-scale projects (requiring multi-stage membrane systems), and situations where CH purity>99% is required.
