Converting CO2 and Heavy Metals recovered from Oil and Gas Wastewater into Carbonates

二氧化碳(CO2)排放是一个巨大的环境问题，特别是在石油开采作业中。 对于艾伯塔省的石油和天然气行业来说，与石油开采、加工、升级和 炼油一直是一个重大挑战，它已经并将限制投资和社会对艾伯塔省原油的接受 油。这里提出的新的研究合作有可能降低油砂的二氧化碳排放。 沥青提炼和升级到低于常规石油生产的水平。Easwara和盖茨博士 将在一个新的合作研究项目中联合他们的独特技能，将Easwara的技术扩展到 包括固定二氧化碳。拟议的研究将使用来自Easwara公司的碳化废料 电凝聚过程与硅酸盐沉淀一起从捕获的二氧化碳或烟道中形成碳酸盐 天然气，例如来自升级机或SAGD工厂(来自蒸汽发生器)。产出的水和 二氧化碳位于同一地点，因此这一过程非常适合将两股废流转化为有用和有价值的产品。

Carbon dioxide (CO2) emissions are a huge environmental problem especially from oil recovery operations. For the Alberta oil and gas industry, CO2 emissions associated with oil extraction, processing, upgrading, and refining has been a major challenge that has and will limit investment and social acceptance of Alberta crude oil. The new research collaboration proposed here has the potential to lower the CO2 emissions of oil sands bitumen extraction and upgrading to a level below that of conventional oil production. Easwara and Dr. Gates will unite their unique skillsets in a new collaborative research project to extend Easwara's technology to include CO2 fixation. The proposed research will use the carbonating wastes from Easwara's electrocoagulation process together with silicate precipitation to form carbonates from captured CO2 or flue gas, for example from an upgrader or SAGD plant (from the steam generator). Both the produced water and CO2 are co-located so this process fits ideally to convert two waste streams to a useful and valuable product.
