The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project will improve the use of water for the oil and gas (O&G) industry, especially during hydraulic fracturing, transforming the industry into a producer of fresh water and changing produced water from its current status as a waste product to a commodity. The proposed technology creates two reusable products: purified water and heavy brine. In addition to the high cost, disposal of produced water through deep injection wells has recently been linked to seismic activity and may impact groundwater quality, prompting policy solutions. The O&G industry competes with other water uses, especially in US arid regions where significant O&G production occurs. Produced water, contaminated with salts, hydrocarbons, and metals, is generated each year through O&G production, costing $37B to manage in the U.S. Current demand for global fresh water resources for agricultural, industrial or domestic purposes is increasing, primarily due to reduction of water supplies in areas affected by drought, climate change, population growth, and expanding industries, as well as degradation of water quality due to contaminants from industry, flooding, or runoff. The proposed project will provide a new treatment for water used in O&G production, creating a renewable source of fresh water from otherwise unusable wastewater or impacted water sources.This SBIR Phase II project proposes to advance the development of an innovative thermal distillation treatment system for produced water generated during O&G production. Current treatment technologies, like reverse osmosis, cannot handle the high-total dissolved solids (TDS) content of most produced water, and thus only a small portion may be reused currently. Disposal is generally through permitted deep injection wells, with water transportation typically serving as the largest disposal cost component. The proposed system accomplishes the entire thermal distillation process in one piece of equipment - a technological advance over state-of-practice thermal distillation units requiring separate energy sources, heat transfer, distillation, separation, and condensation units. It reduces manufacturing and maintenance costs, and it uses less energy in operation. The system can be set up on-site at the well, eliminating the need to transport produced water off-site for disposal. The proposed treatment process yields two reusable products: (1) purified water, which may be sold for use at the well site, sold for agriculture/industrial uses, or discharged to surface waters; and (2) heavy brine, which may be sold as a drilling fluid.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力将改善石油和天然气（O G）行业的用水，特别是在水力压裂过程中，将该行业转变为淡水生产商，并将采出水从目前的废物产品转变为商品。这项技术创造了两种可重复使用的产品：纯净水和浓盐水。除了高成本外，通过深注入威尔斯井处理采出水最近与地震活动有关，可能影响地下水质量，促使采取政策解决办法。 O G行业与其他用水竞争，特别是在美国干旱地区，O G生产量很大。受盐、烃和金属污染的采出水每年通过O G生产产生，在美国管理成本为370亿美元。目前，用于农业、工业或家庭目的的全球淡水资源的需求正在增加，主要是由于受干旱、气候变化、人口增长和工业扩张影响的地区的供水减少，以及由于工业、洪水或径流污染物造成的水质退化。 拟建项目将为O G生产中使用的水提供一种新的处理方法，从其他不可用的废水或受影响的水源中创造可再生的淡水来源。该SBIR二期项目建议推进O G生产过程中产生的采出水的创新热蒸馏处理系统的开发。目前的处理技术，如反渗透，不能处理大多数采出水的高总溶解固体（TDS）含量，因此目前只有一小部分可以重复使用。处置通常通过允许的深注入威尔斯井进行，水运输通常是最大的处置成本组成部分。所提出的系统在一台设备中完成整个热蒸馏过程-这是一项技术进步，超过了需要单独能源、传热、蒸馏、分离和冷凝单元的实际热蒸馏单元。它降低了制造和维护成本，并且在操作中使用更少的能源。 该系统可在油井现场安装，无需将采出水运至场外进行处置。所提出的处理工艺产生两种可重复使用的产品：（1）净化水，其可以出售用于井场，出售用于农业/工业用途，或排放到地表沃茨;（2）浓盐水，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查进行评估，被认为值得支持的搜索.
