Study the Impact of Composite Sample Mixing Methodology and Centrifugal Forces on Density Determination and S & W Results

加拿大拥有广泛和多样化的能源资源组合，生产大量能源供国内消费和出口。大约三分之二的原油产量用于出口，这使得管道工业至关重要。通过管道输送的原油在密度、粘度、含硫量和其他流体性质方面变化很大。当产品在整个管道系统中运输时，它会经过各方的保管。在这些“托管转移”事件中，双方都关心原油的数量和质量，因为这决定了交易的货币价值。为了确定被运输石油产品的“真实体积”，准确测定密度、沉积物和水（S&W）至关重要，这需要适当的样品混合和处理程序。NAIT的油砂可持续发展中心将与国际管道研究理事会（PRCI）、Enbridge Pipeline Inc.、和TransCanada研究复合样品混合方法和离心力对密度和S&W测定的影响。将采用两种不同的混合系统，允许对每个混合系统进行两种密度测量方法和两种S&W含量测定方法。对所收集的数据进行比较将提供有关混合方法和离心力对液体原油密度和S&W测定的影响的重要信息，促进现有ASTM/API的改进。该项目对于提高整个管道社区的监管转移过程的准确性以及提高加拿大在国内和国际上运输原油的能力至关重要。

Canada has a vast and diversified portfolio of energy resources and produces large quantities of energy for bothdomestic consumption and export. About two thirds of crude oil production is exported, making the pipelineindustry crucially important. Crude oil transported by pipeline varies widely in density, viscosity, sulfurcontent, and other fluid properties. As the product is transported throughout the pipeline system, it passesthrough the custody of various parties. During these "custody transfer" events, both parties are concerned withthe quantity and the quality of the crude oil since this determines the monetary value of the transaction. In orderto establish the 'true volume' of the petroleum products being transported, accurate determination of the densityand sediment and water (S&W) is crucial, which requires proper sample mixing and handling procedures.NAIT's Centre for Oil Sands Sustainability will work with Pipeline Research Council International (PRCI),Enbridge Pipeline Inc., and TransCanada to investigate the impact of composite sample mixing methodologyand centrifugal forces on both density and S&W determination. Two different mixing systems will beemployed allowing two methods for density measurement and two methods for S&W content determination tobe conducted for each mixing system. Comparison of the data collected will provide important informationabout the impact of mixing methodology and centrifugal force on density and S&W determination of liquidcrudes, promoting improvements to existing ASTM/API. This project is critical to improve the accuracy ofcustody transfer processes throughout the pipeline community and to enhance Canada's ability to transportcrude oil domestically and internationally.
