In this project we will develop an in-situ monitoring system which can be submerged in a fluid tailing pond to measure the amount of solids in a solid-liquid mixture at various depths of the fluid. The subsurface solids content analyzer combining optical and safe gamma ray methods for in-line continuous monitoring of oil sands processes. The project is a collaborative effort of University of Alberta (U of A) and Centre for Oil Sands Sustainability (COSS), an applied research centre at Northern Alberta Institute of Technology (NAIT), in partnership with Canada's Oil Sands Innovation Alliance (COSIA). We will thoroughly study the processes in laser light scattering from settling particulates and gamma ray propagation in complex materials (tailings). Based on this knowledge, we will design, build and test hybrid optical-gamma ray in-situ solid content analyzer systems for fluid tailings ponds. The technology can be implemented at remote oil sands tailing ponds to measure settling of tailing in real time with lateral and depth spatial resolutions. This technology can be incorporated by oil sands industry into the overall design of their oil sands projects to deliver a more effective process and improved environmental performance.

在这个项目中，我们将开发一个原位监测系统，它可以淹没在一个流体尾矿池，以测量固体的量在固液混合物在不同深度的流体。结合光学和安全伽马射线方法的地下固体含量分析仪，用于油砂工艺的在线连续监测。该项目是阿尔伯塔大学（U of A）和油砂可持续发展中心（COSS）的合作努力，该中心是北方阿尔伯塔理工学院（NAIT）的应用研究中心，与加拿大油砂创新联盟（COSIA）合作。我们将深入研究激光从沉降颗粒散射和伽马射线在复杂材料（尾矿）中的传播过程。基于这些知识，我们将设计、建造和测试用于流体尾矿池的混合光学-伽马射线原位固体含量分析仪系统。该技术可以在偏远的油砂尾矿库中实施，以真实的时间测量尾矿的沉降，具有横向和深度空间分辨率。油砂行业可以将这项技术纳入其油砂项目的整体设计中，以提供更有效的工艺和改善的环境绩效。
