Oil & Gas wells frequently produce a mixed stream of gas, liquid hydrocarbons and water, which either flows or is pumped to the surface and separated. After the oil and/or gas is recovered, the produced water isconventionally disposed of by reinjection into a disposal well. In cold weather climates, there is a danger of the mixed stream freezing or hydrating, so a de-icer/hydrate inhibitor (commonly methanol) is injected into themixed streams. The water stream injected into disposal wells can consist of as much as 90% methanol. TheSouthern Alberta Institute of Technology and their industry partner, ChampionX, are focused on the recovery and recycling process of methanol from wastewater. SAIT's Centre for Energy Research and CleanUnconventional Technologies (CERCUTS) will collaborate with the partner to optimize the current Methanol Recovery Technology (MRT) process through designing, assembling and analyzing a novel, high performance water pre-treatment system that will be integrated within one of the three recovery pilot units that are inAlberta. Implementing an enhanced technology of this type would provide Canada with environmental benefitsby reducing disposal of the methanol used as de-icer in produced water by up to 90%. The recovered methanol can be recycled in SAGD and other Oil & Gas operations, or sold to alternative consumers as a byproduct.MRT can also be used for recovery of methanol within the Canadian pulp and paper and pharmaceuticalindustries. The recovery and recycling of methanol will have a positive environmental impact by keepingcarbon in a closed loop, reducing greenhouse gas emissions caused by incineration and eliminating leaking and spill risks associated with conventional waste disposal. This also provides the industry the ability to treatprocessed water to be reused in operations, reducing the need for clean water sources.

石油和天然气威尔斯井经常产生气体、液态烃和水的混合流，其流动或被泵送到地面并分离。在油和/或气被回收之后，采出水通常通过回注到处置井中来处置。在寒冷的气候条件下，存在混合流冻结或水合的危险，因此将除冰剂/水合物抑制剂（通常为甲醇）注入混合流中。注入处理威尔斯井的水流可以由高达90%的甲醇组成。南阿尔伯塔理工学院和他们的行业合作伙伴AlbertonX专注于从废水中回收和再循环甲醇的过程。SAIT的能源研究和清洁非常规技术中心（CERCUTS）将与合作伙伴合作，通过设计、组装和分析一种新型、高性能的水预处理系统来优化当前的甲醇回收技术（MRT）工艺，该系统将集成到其中一个中。阿尔伯塔省的三个回收试点装置。实施这种类型的增强技术将为加拿大提供环境效益，减少高达90%的用于采出水除冰剂的甲醇的处置。回收的甲醇可以在SAGD和其他石油和天然气操作中回收，或作为副产品出售给替代消费者。MRT也可以用于加拿大纸浆和造纸以及制药行业的甲醇回收。甲醇的回收和再循环将产生积极的环境影响，使碳保持在一个封闭的循环中，减少焚烧造成的温室气体排放，消除与传统废物处理有关的泄漏和溢出风险。这也为行业提供了处理处理水的能力，以在运营中重复使用，减少对清洁水源的需求。
