Oil sands processing is carried out on a very large scale, and meaningful scale-down studies to support new process design and development are essential to both innovation and long term growth of the industry. In scaled-down batch liquid-liquid mixing experiments, the challenge is to find a physically meaningful and scalable set of mixing variables, and a mixing geometry which allows those variables to be successfully and accurately applied in the design of a full-scale vessel. Ideally, a bench scale test should use 1L or less of sample, while an industrial scale vessel in the oil sands industry may hold 10 000 L or more. A test cell is proposed in this work which would allow such standardized mixing tests to be carried out for the oil sands

油砂加工是以非常大的规模进行的，有意义的缩小规模研究以支持新工艺的设计和开发对于该行业的创新和长期增长至关重要。在按比例缩小的批量液-液混合实验中，挑战在于找到一组物理上有意义且可扩展的混合变量，以及允许这些变量成功且准确地应用于全尺寸容器设计中的混合几何形状。理想情况下，实验室规模测试应使用1 L或更少的样品，而油砂行业的工业规模容器可容纳10 000 L或更多。在这项工作中提出了一个测试单元，它将允许对油砂进行这种标准化的混合测试
