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，该系统可以浸入流体尾池中，以测量在流体各个深度的固液混合物中的固体量。地下固体内容分析仪结合了光学和安全伽马射线方法，用于在线连续监测油砂过程。该项目是艾伯塔大学（U）大学（A）的合作努力，也是北艾伯塔省理工学院（NAIT）的应用研究中心（COSS）（COSS），与加拿大的油沙创新联盟（Cosia）合作。我们将彻底研究来自沉降颗粒的激光光散射和复杂材料（尾矿）中的伽马射线传播的过程。基于这些知识，我们将设计，构建和测试用于流体尾矿池的原子固体含量分析仪系统。该技术可以在偏远的油砂尾部池塘实施，以通过横向和深度空间分辨率实时测量尾巴的沉降。油砂行业可以将这项技术纳入其油砂项目的总体设计中，以提供更有效的过程和改善的环境绩效。
