项目摘要

Canada is well positioned to deliver safe, secure, and reliable energy to markets especially via steam-assisted in-situ production of oil sands deposits. This requires highly economic approaches to produce steam in so-called Once Through Steam Generators (OTSGs) while produced fluids are recycled to minimize the environmental footprint of in-situ oil sands operations. The boiler feed water constituents are prone to cause mineral and organic precipitates upon heating in steam generators and erosion and corrosion often resulting in premature OTSG failure. The objective of this research project is to reduce inorganic and organic fouling and erosion and corrosion in OTSGs to enhance water and energy efficiency and achieve greenhouse gas emission reductions. The research team members from the University of Calgary, the University of Alberta, and SAIT will advance the scientific knowledge about inorganic and organic fouling, erosion and corrosion, and modeling of OTSG systems. A unique aspect of this project is the ability to test the applicability of key findings from laboratory and modeling investigations in two large-scale pilot test OTSG rigs. The inter-disciplinary evaluation and interpretation of the research activities will create for the first time a scientifically based technical operating envelope (TOE) for steam generators. An improved scientific knowledge of boiler feed water limits (e.g. hardness, dissolved silica content, content and quality of organic compounds among others) will enable higher steam qualities of up to 90%. This will result in a more economic and environmentally friendly operation of OTSGs and hence in a significantly increased competitive advantage for oil from Canada's large in-situ oil sands reserves.

加拿大处于良好的位置，可以通过蒸汽辅助油砂沉积物的原位生产为市场提供安全，安全和可靠的能源。这需要高度经济的方法来通过蒸汽发生器（OTSG）产生一次所谓的蒸汽，而生产的液体则被回收，以最大程度地减少原地油砂操作的环境足迹。锅炉馈电水成分容易引起蒸汽发生器加热后的矿物质和有机沉淀，腐蚀和腐蚀通常会导致过早的OTSG失败。该研究项目的目的是减少OTSG中无机和有机污染和腐蚀和腐蚀，以增强水和能源效率并实现温室气体排放的减少。卡尔加里大学，艾伯塔大学和SAIT的研究小组成员将促进有关无机和有机污染，侵蚀和腐蚀以及OTSG系统建模的科学知识。该项目的一个独特方面是能够在两个大规模试验测试OTSG钻机中测试实验室和建模研究的关键发现的适用性。研究活动的跨学科评估和解释将首次创建基于科学的技术操作信封（TOE），用于蒸汽发生器。锅炉供水限制（例如硬度，溶解的二氧化硅含量，有机化合物的含量和质量）的科学知识将使高达90％的蒸汽品质提高。这将导致OTSG的经济和环境更加友好的运作，因此，来自加拿大大型原地油砂储量的石油的竞争优势显着提高。
