SBIR Phase II: A Novel Metal-Organic Framework Material for the Separation and Recovery of Unprocessed Natural Gas During Oil and Gas Production

这个小企业创新研究第二阶段项目的更广泛的影响/商业潜力是为石油和天然气勘探公司提供可用的搁浅和相关的天然气收集能力。在钻井作业中，有价值的天然气通过故意的通风和燃烧而损失，导致输送到发电厂或城门的天然气损失。随着该行业向更偏远、低交易量的地点扩张，这些损失正在急剧增加。通过该项目提出的基于金属有机框架(MOF)的新型存储技术，该项目寻求提供一种可重复使用且便于运输的多式联运集装箱，以在低压下存储天然气，从而消除使用昂贵的气体捕获、净化和多级压缩系统的需要。一种经济上可行的未经加工的天然气储存技术，将为国内油气行业提供一个有用的工具，以捕捉可能燃烧或排放的天然气，并将其输送到美国经济。将拟议的新型MOF技术用于试验台和中试规模，将表明建立一种灵活、可运输、低成本的基础设施来抑制燃烧和泄气的可行性。该项目的成功开发将有助于发展扩大到大型车用储罐的知识，以便进行商业实施。该第二阶段研究项目的目标是开发稳定和低成本的基于金属-有机骨架(MOF)的存储技术，用于在钻井作业期间收集可用的搁浅伴生气体。为了利用点源排放，在排放或燃烧之前，该项目将开发一种纳米工程的MOF基吸附剂，用于低压捕获和储存未加工的天然气。该项目将寻求开发一种稳健且可扩展的方法来合成包含其他高价过渡金属离子如Al3+、Fe3+和Cr3+的新的MOF。此外，该项目将筛选一系列有机配体，以改善MOF的表面性质和存储能力。最后，通过遵循低成本催化剂的替代合成路线，该项目将确定降低吸着剂合成成本的策略。吸着剂材料将在循环压力范围内用模拟通风口/火炬气体成分进行测试，吸着剂的稳定性将通过各种X射线、光谱分析和显微镜方法进行验证。随着吸附剂的开发，将建造一个ANG储罐，并将在页岩气现场进行火炬气滑流测试。

The broader impact/commercial potential of this Small Business Innovation Research Phase II project is to provide a usable stranded and associated gas collection capacity for oil & gas exploration companies. During drilling operations, valuable gas is lost through intentional venting and flaring, causing losses in natural gas delivered to the power plant or city gate. With the sector's expansion into more remote low-volume sites, these losses are increasing dramatically. Through this project's proposed novel Metal-Organic Framework (MOF) based storage technology, this project seeks to deliver a re-usable and transport ready intermodal container, to store gas at low pressure, eliminating the need to use expensive gas capture, purification and multi-stage compression systems. An economically feasible unprocessed natural gas storage technology would provide a useful tool for the domestic oil & gas industry in capturing what would be flared or vented and delivering it to the American economy. Taking the proposed novel MOF technology to the bench and pilot scale will show the feasibility of a flexible, transportable, low-cost infrastructure to abate flaring and venting. Successful developments in this project will help develop the knowledge for scale-up to large-scale vehicular tanks to allow for commercial implementation.The objectives of this Phase II research project are the development of stable and low-cost Metal-Organic framework (MOF) based storage technologies for the collection of usable stranded associated gas during drilling operations. In order to harness point source emissions, before being vented or flared, the project will develop a nano-engineered, MOF based sorbent for low-pressure capture and storage of unprocessed natural gas. The project will seek to develop a robust and scalable method to synthesize new MOFs containing other high-valence transition metal ions such as Al3+, Fe3+ and Cr3+. Furthermore, the project will screen a range of organic ligands for improving MOFs' surface property and storage capacity. Finally, by following alternative synthesis routes with low cost catalysts, the project will identify sorbent synthesis cost reduction strategies. The sorbent material will be tested with simulated vent/flare-gas compositions in a cyclic pressure range and the sorbent stability will be verified by an assortment of X-ray, spectroscopy, and microscopy methods. Following sorbent development, an ANG tank will be built and flare gas slipstream testing will be conducted in shale gas sites.
