Bitumen transportation by pipelines requires dilution with solvents. These diluents are often expensive. Therefore, the utilization of liquid CO2 as a diluent to reduce or eliminate consumption is interest. However, there limited data in literature on liquid-liquid equilibrium (LLE) and bitumen. In this work, we report new set LLE for MacKay River bitumen at ambient temperature. First, bitumen/CO2 various feed concentrations was studied. The density light heavy phases, viscosity phase, phase...
We report new measurements and correlations of the density, viscosity, solubility, K-values multicomponent solvent/live bitumen systems with applications to solvent-aided thermal recovery bitumen. The live a solvent composed n-C4, n-C5, n-C6, n-C8, n-C10 were measured at pressure range 1–6 MPa temperature 343.15–503.15 K. A systematic approach is presented that can be adapted for construction input PVT models reservoir simulations. data are correlated temperature- pressure-dependent used in...
The in situ solvent-aided thermal recovery processes are promising methods for recovering unconventional oil resources due to their higher efficiency, lower energy and water consumption, reduced environmental impacts. produced stream is often a highly stable water-in-oil emulsion, where the phase comprises bitumen solvent. Separating from such sample challenging because conventional approaches result solvent loss contamination render content measurement techniques currently employed by...
This study presents an experimental evaluation of the ES-SAGD process to better understand recovery mechanisms, determine optimized solvent concentrations, and enhance overall efficiency. Conducting three-dimensional physical model experiments (3DPMEs) poses significant challenges due their complexity, cost, labor intensity, time requirements. In this work, 3DPMEs were performed using varying concentrations natural gas condensate as a solvent, chosen for its field availability...
Solvent-aided thermal recovery processes have been suggested and implemented to reduce the environmental impact of steam-based heavy oil bitumen production. The injected solvents often undergo dissolution (exsolution) into (from) phase throughout processes. New experimental data at elevated pressures temperatures are essential better understand kinetics various solvents. To eliminate this gap, a new setup was developed study exsolution gases. used ethane from ethane-saturated heptane in...
The kinetics for the reaction of carbon dioxide with primary 3-(dimethylamino)-1-propylamine (DMAPA) in water and methanol systems were investigated using stopped-flow technique over a temperature range 298.15–313.15 K. Pseudo-first-order rate constants (CO2 + DMAPA) aqueous at K estimated concentrations ranging from 40 to 150 mol·m–3 100 300 mol·m–3, respectively. Both Zwitterion termolecular mechanisms successfully correlated experimentally observed pseudo-first-order constants....
The study aimed to investigate the partial upgrading of bitumen in absence water (non-water) and presence supercritical (SCW). Partial experiments were conducted at target temperature 420 °C, with reaction time varying from zero 60 min a batch reactor. liquid products analyzed for density, viscosity, composition, total acid number (TAN), olefin content, elemental analysis. gas composition morphology solid also studied. experimental results revealed that while SCW could accelerate improvement...
We present experimental findings of Rayleigh–Taylor (RT) instability within porous materials, with a significant viscosity contrast M ≈ 106, where represents the ratio dynamic heavy fluid to that light fluid, = μH/μL, and Ra 6.62 × 104–6.67 105, Rayleigh number (Ra) quantifies relative significance buoyancy forces compared viscous forces. observe lighter diffuses into denser one, creating transient diffusive boundary layer rapidly becomes unstable, transitioning convection-dominated regime....
A new method has been established to make rice based ORS through absorption of salts in by soaking the solution salts. The soaked was dried, fried, powdered and packaged. powder thus prepared when mixed with water desired proportion, suspensions contain Na+, K+ Cl- as prescribed. process is named ‘solution method’ according preparation procedure.DOI: 10.3329/cerb.v13i2.3132Chemical Engineering Research Bulletin 13 (2009) 47-50
