Sorption columns for the remediation of SAGD and tailings ponds water

湖和和平河。该矿床已探明储量约1680亿桶，是仅次于阿拉伯和委内瑞拉的世界第三大已探明原油储量。考虑到预计的全球石油需求，加拿大的油砂代表着一个巨大的经济机会，预计在未来25年内将会增长。在露天开采和以蒸汽为基础的现场作业中，水对于从油砂中回收沥青是必不可少的。最著名的蒸汽基原地开采工艺是蒸汽辅助重力排水(SAGD)。为了减少用水需求，油砂作业者回收80%-95%的水，并尽可能使用咸水。考虑到预计的扩张和水油比，通过有效的水循环将补水降至最低，对于油砂作业的可持续性至关重要，从而对加拿大经济也是至关重要的。目前的处理方案要么受到主要固体废物副产品的影响(与化学处理机组有关)，要么受到高额能源惩罚(与蒸发器机组有关)。找到一辆坚固的列车/机组，能够抵抗工艺中受影响的水或生产水中的许多污染物的影响是至关重要的。这项工作建议使用填充了膦表面活性剂的吸附柱来修复脱油水。磷酸盐表面活性剂具有很高的去除脱油水中硬度、有机和二氧化硅污染的潜力。斯坦泰克是水处理领域的行业领先者，一直在寻找新的创新技术，特别是在SAGD运营的产出水处理方面。

Lake and Peace River. With approximately 168 billion barrels of proven reserves, this deposit is the thirdlargest proven crude oil reserve in the world following the Arabia and Venezuela. Given the projected globaldemand on oil, Canada's oil sands represent a big economic opportunity, which is expected to grow over thenext 25 years. Water is essential for the recovery of bitumen from oil sands during surface mining andsteam-based in situ operations. The most famous steam-based in situ recovery process is Steam AssistedGravity Drainage (SAGD). In an effort to reduce water demand, oil sands operators recycle 80-95 per cent ofthe water and use saline water where possible. Given the projected expansion and the water to oil ratio,minimizing makeup water through effective water recycling is essential for the sustainability of oil sandsoperations, and hence the Canadian economy. Current treatment schemes either suffer from major solid wastebyproduct (associated with the chemical treatment train) or high energy penalty (associated with the evaporatortrain). Finding a robust train/unit that can resist the impact of the many contaminants in process affected wateror produce water is essential. This work proposes the use of sorption columns packed with phosphinatesurfactant for the remediation of de-oiled water. The phosphinate surfactant display high potential of removinghardness, organic and silica contamination from the de-oiled water.Stantec is an industry leader in water treatment and is always on the look for new innovative technologies,especially when it comes to produced water treatment from SAGD operations.
