Sorption columns for the remediation of SAGD and tailings ponds water

和平河与和平湖该存款已探明储量约1680亿桶，是继阿拉伯和委内瑞拉之后世界第三大已探明原油储量。考虑到全球对石油的预期需求，加拿大的油砂代表了一个巨大的经济机遇，预计在未来25年内将继续增长。在露天开采和基于蒸汽的原位操作过程中，水对于从油砂中回收沥青至关重要。最著名的基于蒸汽的原位开采工艺是蒸汽辅助重力泄油（SAGD）。为了减少水需求，油砂运营商回收80- 95%的水，并在可能的情况下使用盐水。考虑到预计的扩张和水油比，通过有效的水循环来减少补充水对于油砂作业的可持续性以及加拿大经济至关重要。目前的处理方案要么遭受主要的固体废物副产品（与化学处理机组相关），要么遭受高能量损失（与蒸发机组相关）。找到一个强大的火车/单位，可以抵御许多污染物的影响，在过程中受影响的水或生产水是必不可少的。本工作提出了使用吸附柱填充次膦酸酯表面活性剂的修复脱油水。次膦酸盐表面活性剂具有很高的去除脱油水中的硬度、有机物和二氧化硅污染的潜力。Stantec是水处理领域的行业领导者，一直在寻找新的创新技术，特别是在SAGD操作的采出水处理方面。

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.
