Feasibility of Solvent Replacement in Current Measurement Methods of Sediment and Water Content in Crude

北阿尔伯塔理工学院（NAIT）油砂可持续发展中心（COSS）成立于2010年，与业界合作验证和优化创新技术，以提高加拿大油砂的环境和经济效益。COSS将与国际管道研究委员会、TransCanada和Enbridge合作，研究用溶剂替代原油样品中沉积物和含水量测定方法的可行性。本研究包括广泛的文献综述，以筛选有前途的溶剂，评估替代溶剂，以取代甲苯用于目前的离心沉淀物和重质原油的水测定方法。目标是减少一线工作人员长期接触有毒和危险溶剂的风险，减少危险液体废物的处置负荷，并减少潜在的环境污染。

The Northern Alberta Institute of Technology (NAIT) Centre for Oil Sands Sustainability (COSS), established in 2010, collaborates with industry to validate and optimize innovative technologies with the potential to enhance the environmental and economic performance of Canada's oil sands. COSS in collaboration with Pipeline Research Council International, TransCanada, and Enbridge will study the feasibility of solvent replacement for the current methods of sediment and water content determination in crude samples. This study includes extensive literature review to screen promising solvents, evaluation of alternative solvents to replace toluene used for the current centrifuge method for sediment and water determination of light and heavy crudes. The goal is to reduce the risks of prolonged exposure to toxic and hazardous solvents for frontline workers, decrease the disposal load of hazardous liquid waste, and reduce potential environmental contamination.
