Dundee Energy Ltd. is an international oil and gas processing company that manages offshore natural gas and onshore light oil reserves in and around Lake Erie, Ontario. Dundee operates and maintains two drilling rigs and has compression and processing facilities on shore. By managing reserves that are close to industrial consumers and existing utility infrastructure, Dundee Energy is able to minimize operational, storage, and transportation costs, and secure long-term sales contracts. Dundee is seeking a cost effective process to improve their raw natural gas product stream, which contains residual undesired hydrocarbons. The presence of undesired hydrocarbons reduces the methane content of natural gas, and to be saleable, it must be diluted with cleaner natural gas from other wells. When undesired hydrocarbon content is high, and the availability of clean natural gas for mixing is low, the natural gas does not meet utility specifications. Consequently this gas cannot be sold to consumers, and the time and energy used to extract the gas are not compensated for. Dundee Energy has approached Dr. Tezel at the University of Ottawa for her expertise in this first-time collaboration to perform experiments to examine the potential use of adsorptive silicalite membranes to separate undesired hydrocarbons with 4 or a higher number of carbons (C4+) in their structure (e.g., butane, isobutane, pentane, etc.) from methane, which is the most significant component of natural gas. In this study, new silicalite membranes will be designed and prepared and the effects of operating pressure, and feed gas composition in particular, will be investigated in the lab for these membranes. The best membrane will be demonstrated at Dundee Energys Windsor facilities. Different membranes, as well as separation processes will be developed that Dundee Energy will be able to take to the market at the end of this study.

Dundee Energy Ltd. 是一家国际石油和天然气加工公司，管理海上天然气和陆上灯光 安大略省伊利湖及其周边地区的石油储量。邓迪运营和维护两台钻机，并拥有压缩和 岸上的加工设施。通过管理靠近工业消费者和现有公用事业基础设施的储备， Dundee Energy 能够最大限度地降低运营、储存和运输成本，并获得长期销售合同。 邓迪正在寻求一种具有成本效益的工艺来改善其原始天然气产品流，其中含有残余物 不需要的碳氢化合物。不需要的碳氢化合物的存在会降低天然气中的甲烷含量，并且 如果要出售，必须用其他井中的更清洁的天然气进行稀释。当不需要的碳氢化合物含量较高时，并且 用于混合的清洁天然气的可用性较低，天然气不符合公用事业规范。因此这 天然气不能出售给消费者，提取天然气所花费的时间和能源也得不到补偿。邓迪能源公司 已联系渥太华大学的 Tezel 博士，了解她在首次合作进行实验方面的专业知识 检查吸附硅沸石膜分离不需要的碳氢化合物（4 或更高）的潜在用途 其结构（例如丁烷、异丁烷、戊烷等）中的碳数 (C4+) 来自甲烷，这是最多的 天然气的重要组成部分。 在这项研究中，将设计和制备新型硅沸石膜，以及操作压力和原料气的影响 特别是成分，将在实验室中对这些膜进行研究。最好的膜将在 邓迪能源温莎工厂。邓迪将开发不同的膜以及分离工艺 在这项研究结束时，能源将能够进入市场。
