SBIR Phase I: Multilayer Membrane-Based Permeation for Cost-Effective Olefin/Paraffin Separation

这个小型企业创新研究（SBIR）一期项目将开发分离烯烃/石蜡混合物的气体渗透工艺和膜，其中多层多功能膜配置确保了高选择性、高烯烃生产率、良好的机械稳定性、优异的杂质耐受性和长期运行可靠性。将开发中空纤维膜组件，使其烯烃渗透率比传统聚合物促进传输膜提高2~10倍，并大大提高了烯烃/石蜡的选择性。该膜系统对于含有微量H2、C2H2和/或H2S的饲料具有长期的稳定性和可靠性，而传统的膜工艺无法处理这些饲料。与其他膜工艺相比，该工艺更具发展前景和成本效益。如果开发成功，它将广泛应用于烯烃/石蜡的分离。

This Small Business Innovation Research (SBIR) Phase I project will develop a gas permeation process and membrane to separate olefin/paraffin mixtures in which a multilayer multifunctional membrane configuration ensures high selectivity, high olefin productivity, good mechanical stability, excellent impurity tolerability, and long-term operational reliability. Hollow fiber membrane modules will be developed to enhance the olefin permeance 2~10-fold compared to those by conventional polymer facilitated transport membranes in addition to much enhanced olefin/paraffin selectivity. This membrane system has long-term stability and reliability to dry feed containing trace amounts of H2, C2H2, and/or H2S that cannot be treated by traditional membrane processes. Compared to the other membrane processes, this process is more promising and cost-effective. If successfully developed, it could be applied very widely to olefin/paraffin separations.
