Reference number : GC-2017-Q4-00441, amendment number : , agreement type : G, recipient legal name : De Lasa, Hugo (The University of Western Ontario), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Collaborative Research and Development Grants - Project, program name french : Subventions de recherche et développement coopérative - projet, program purpose english : The goal of the present study is to develop a new thermodynamic model for the simulation of the saturation_x000D_
vapour pressure in Dilbit-water-sand/clay slurries, in proportions relevant to the NRU (Naphtha Recovery Unit)_x000D_
and using actual Syncrude NRU Feed samples. Experiments will be developed using a Recat LV Cell, which_x000D_
has been tested and implemented by Prof. de Lasa's team at the CREC(Chemical Reactor Engineering Centre)_x000D_
-UWO (University of Western Ontario) laboratories. The Recat LV Cell allows the quantification of the vapour_x000D_
pressure, as well as the identification of adequate mixing slurry conditions. In this respect, the proposed new_x000D_
research under combined NSERC CRD and Syncrude Canada sponsorship will involve enhancing the Recat_x000D_
LV Cell further. The patented CREC Optiprobes will be used for gas phase sampling as well as online_x000D_
measurement of droplets and particle sizes. It is anticipated that the use of this strategy will provide critical_x000D_
data for the identification of best mixing conditions and power input, for highly dispersed_x000D_
Dilbit-water-sand/clay slurry phases and NRU feeds. Furthermore, a Computational Fluid Dynamic (CFD)_x000D_
model will be developed for this test cell. The proposed CFD model will be validated using data from the Recat_x000D_
LV Cell. This model will also use relevant fluid dynamic parameters for CFD simulation such as viscosity,_x000D_
surface tension and sand agglomerate sizes. This CFD model will provide a description of mixing patterns in_x000D_
the Recat LV Cell and the best conditions required for achieving liquid-vapour equilibrium. These identified_x000D_
mixing conditions, as well of liquid-vapour thermodynamics will provide Syncrude valuable engineering_x000D_
information for the efficient processing of their Froth Treatment tailings and fine tune their operation for_x000D_
