Methanol Recovery - Wastewater Recovery

油气井经常产生混合的气体、液态碳氢化合物和水，这些气体要么流动，要么被泵送到地面并分离。在石油和/或天然气被回收后，采出的水通常通过重新注入处理井来处理。在寒冷的气候条件下，混合流有冻结或水合的危险，因此向混合流中注入除冰剂/水合物抑制剂(通常是甲醇)。注入处理井的水流中可能含有高达90%的甲醇。南艾伯塔省理工学院和他们的行业合作伙伴冠军X专注于废水中甲醇的回收和再循环过程。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的高性能水处理系统来优化当前的甲醇回收技术(MRT)工艺，该系统将集成在艾伯塔省三个回收试点装置之一中。实施这一类型的强化技术将为加拿大带来环境效益，将产出水中用作除冰剂的甲醇的处置减少高达90%。回收的甲醇可在SAGD和其他石油天然气业务中循环使用，或作为副产品出售给替代消费者。MRT还可用于加拿大纸浆、造纸和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，使碳排放保持在一个封闭的循环中，减少焚烧造成的温室气体排放，消除与传统废物处置相关的泄漏和溢出风险。这也为该行业提供了处理处理后的水以在运营中重复使用的能力，减少了对清洁水源的需求。

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.
