摘要： The present invention discloses a new type of polyimide membrane with high permeances and high selectivities for gas separations and particularly for CO2/CH4 and H2/CH4 separations. The polyimide membranes have CO2 permeability of 50 Barrers or higher and single-gas selectivity for CO2/CH4 of 15 or higher at 50° C. under 791 kPa for CO2/CH4 separation. The polyimide membranes have UV cross-linkable functional groups and can be used for the preparation of UV cross-linked polyimide membranes having CO2 permeability of 20 Barrers or higher and single-gas selectivity for CO2/CH4 of 35 or higher at 50° C. under 791 kPa for CO2/CH4 separation.

摘要： The present invention involves the use of a novel membrane system for natural gas upgrading. This membrane system includes a first-stage membrane such as a membrane prepared from the polymer of intrinsic microporosity (PIM) to selectively remove hydrocarbons from C3 to C35 to control the dew point of natural gas, and a second-stage membrane such as a polybenzoxazole (PBO) or crosslinked PBO membrane to selectively remove CO2 from natural gas. The new membrane system described in the current invention eliminates the use of high cost and high footprint membrane pretreatment. Therefore, the membrane system can significantly reduce the footprint and cost for natural gas upgrading compared to the current commercially available membrane systems that include a non-membrane-related pretreatment system.
摘要翻译：本发明涉及使用新型膜系统进行天然气升级。该膜系统包括由本征微孔聚合物（PIM）制备的膜的第一级膜，以选择性地从C3至C35去除烃，以控制天然气的露点;以及第二级膜，例如聚苯并恶唑（PBO）或交联的PBO膜以选择性地从天然气中除去CO 2。本发明描述的新膜系统消除了高成本和高占地面积的膜预处理的使用。因此，与目前市场上可买到的膜系统（包括非膜相关的预处理系统）相比，膜系统可显着减少天然气升级的占地面积和成本。
