9860416 This Small Business Innovation Research Phase I project addresses development of economical devices for purification of low-quality raw natural gas to pipeline quality. A large fraction of domestic natural gas reserves are currently uneconomical for recovery based on current market conditions because they contain significant amounts of non-methane gas. Membrane separations have appreciable potential for natural gas purification, but membrane devices with improved productivity over current state-of-the-art devices are required. The overall objective of this program is to develop a novel fabrication approach to incorporate microporous silica membranes into low-cost, highly compact modules. These membranes have high selectivity and extremely high permeability for separation of impurities from methane. Commercial availability of such modules would appreciably reduce costs associated with upgrading of low-quality natural gas resources. In Phase I, the chemistry underlying the novel fabrication approach will be studied. Microporous silica membranes will be incorporated on small support coupons via this approach and their gas permeation characteristics will be measured to demonstrate the technical feasibility of the approach. The gas separation membrane modules to be developed in this program would reduce costs associated with separation of a variety of industrially significant gas streams in applications including natural gas upgrading, carbon dioxide recovery from enhanced oil recovery operations, biogas processing, and helium recovery.

9860416这个小型企业创新研究阶段I项目介绍了经济设备的开发，用于净化低品质的原始天然气到管道质量。目前，基于当前市场条件，大量的家庭天然气储量目前对恢复的经济性不经济，因为它们含有大量的非甲烷天然气。膜分离具有明显的天然气净化潜力，但是需要比当前最新设备的生产率提高的膜设备。 该程序的总体目的是开发一种新型的制造方法，将微孔二氧化硅膜结合到低成本，高度紧凑的模块中。这些膜具有很高的选择性和极高的渗透性，可将杂质与甲烷分离。此类模块的商业可用性将显着降低与升级低质量天然气资源相关的成本。在第一阶段，将研究新型制造方法的基础化学。微孔二氧化硅膜将通过这种方法纳入小型支撑优惠券，并将测量其气体渗透特性以证明该方法的技术可行性。 在该计划中要开发的气体分离膜模块将降低与各种工业意义的天然气流相关的成本，包括天然气升级，二氧化碳从增强的石油回收操作，沼气加工和氦气回收中的恢复。
